This paper presents a new type diode connected MOS transistor to improve CMOS conventional rectifier's performance in RF energy harvester systems for wireless sensor networks in which the circuits are designed in 0.18 μm TSMC CMOS technology. The proposed diode connected MOS transistor uses a new bulk connection which leads to reduction in the threshold voltage and leakage current; therefore, it contributes to increment of the rectifier’s output voltage, output current, and efficiency when it is well important in the conventional CMOS rectifiers. The design technique for the rectifiers is explained and a matching network has been proposed to increase the sensitivity of the proposed rectifier. Five-stage rectifier with a matching network is proposed based on the optimization.

In this article, we present a new method of simultaneously increasing the phase quantity and regulating the rectified voltage for two 12-phase high-power rectifiers operating at a common load. Self-excited voltage inverters separately form the necessary voltages for voltage regulation and for increasing the phase quantity. The formed voltage is input with the help of a common booster transformer. Separating the inverters functions and using the common booster transformer makes it possible to reduce the installed power of the equipment significantly compared to similar circuits when the regulation range of the rectified voltage is up to 5%. Calculations show that the inverter power for increasing the phase quantity is about 3% of the rectifier power. The circuit was modeled in MatLab/Simulink and the electromagnetic processes in the rectifier were studied. The proposed method makes it possible to reduce the total harmonic distortion of the network current and the pulsation coefficient of the rectified voltage to the values typical for 24-phase rectifiers.

Nowadays renewable energy sources play a significant role in the energy harvesting. For the past decade various energy harvesting methods have been discussed by researchers for capturing the energy from different sources. From the survey, one of the most prominent methods is the use of piezoelectric transducers for harvesting the energy. It is known that piezoelectric energy harvesting is the easiest method of energy harvesting from the various sources available such as human walking, dancing etc. Therefore this method can be implemented in system for wide variety of applications. The piezoelectric transducer AC output is of very low voltage and power and hence insufficient to drive any electrical application. Most of the small scale electrical application generally runs on the DC voltage, therefore the AC voltage obtained from the piezo transducer vibration is rectified using rectifiers to generate DC voltage. Thus in this paper, a modified rectifier AC/DC converter with the combination of an inductor is placed in the rectifier, which enhances the voltage and power from the rectifier output. In order to enhance the voltage rating, a DC/DC converter has been added at the end of a rectifier circuit. From the simulation results the proposed circuit modified rectifier has improved the output voltage as well as output current by 10.19 volts and 0.1019 amps respectively for input voltage of 5V. When compared with conventional rectifier circuit.

Full textAbstract:
Harvesting energy from human motion for powering small scale electronic devices is attracting research interest in recent years. A piezoelectric device (PD) is capable of harvesting energy from mechanical motions, in the form of alternating current (AC) voltage. The AC voltage generated is of low frequency and is often unstable due to the nature of human motion, which renders it unsuitable for charging storage device. Thus, an electronic circuit such as a full bridge rectifier (FBR) is required for direct current (DC) conversion. However, due to forward voltage loss across the diodes, the rectified voltage and output power are low and unstable. In addition, the suitability of existing rectifier circuits in converting AC voltage generated by PD as a result of low frequency human motion induced non-sinusoidal vibration is unknown. In this paper, an improved H-Bridge rectifier circuit is proposed to increase and to stabilise the output voltage. To study the effectiveness of the proposed circuit for human motion application, a series of experimental tests were conducted. Firstly, the performance of the H-Bridge rectifier circuit was studied using a PD attached to a cantilever beam subject to low frequency excitations using a mechanical shaker. Real-life testing was then conducted with the source of excitation changed to a human performing continuous cycling and walking motions at a different speed. Results show that the H-Bridge circuit prominently increases the rectified voltage and output power, while stabilises the voltage when compared to the conventional FBR circuit. This study shows that the proposed circuit is potentially suitable for PEH from human motion.

Abstract This research article introduces an innovative full-wave rectifier design centered around the Voltage Differencing Trans-conductance Amplifier (VDTA) as its foundational core, thereby eradicating the necessity for passive components. The proposed circuit demonstrates high linearity and good zero-crossing performances. The rectified output signal can be adjusted by controlling the bias currents. Its simple and compact design makes it well-suited for integration into IC circuits, especially for low-voltage, high-frequency applications. A detailed analysis of the proposed rectifier includes evaluating non-ideal effects and parasitic influences. By eliminating passive components, the circuit minimizes parasitic effects. Its robustness is evaluated through detailed simulations using 0.18 μm CMOS technology and a ±0.8 V power supply, showing strong agreement with theoretical predictions. Additional reliability insights are obtained via Monte Carlo simulations and corner analysis. To verify the rectifier’s feasibility, practical experiments with off-the-shelf components confirm its functionality and efficiency. The circuit layout is implemented in Cadence Virtuoso, occupying a chip area of 2726 μm2.

Full textAbstract:
A compact, single-layer microstrip rectenna for dedicated far-field RF wireless power-harvesting applications is presented. The proposed rectenna circuit configurations including multiband triple L-Arms patch antenna with diamond slot ground are designed to resonate at 10, 13, 17, and 26 GHz with 10 dB impedance bandwidths of 0.67, 0.8, 2.45, and 4.3 GHz, respectively. Two rectifier designs have been fabricated and compared, a half wave rectifier with a shunted Schottky diode and a voltage doubler rectifier. The measured and simulated maximum conversion efficiencies of the rectifier using the shunted diode half-wave rectifier are 41%, and 34%, respectively, for 300 Ω load resistance, whereas they amount to 50% and 43%, respectively, for voltage doubler rectifier with 650 Ω load resistance. Compared to the shunted rectifier circuit, it is significant to note that the voltage doubler rectifier circuit has higher efficiency. Both rectifier’s circuits presented are tuned for a center frequency of 10 GHz and implemented using 0.81 mm thick Rogers (RO4003c) substrate. The overall size of the antenna is 16.5 × 16.5 mm2, and the shunted rectifier is only 13.3 × 8.2 mm2 and 19.7 × 7.4 mm2 for the voltage doubler rectifier. The antenna is designed and simulated using the CST Microwave Studio Suite (Computer Simulation Technology), while the complete rectenna is simulated using Agilent’s ADS tool with good agreement for both simulation and measurements.

The demand for increased voltage in renewable energy sources is relatively high. This study examines the rapid development of technology considering the use of voltage-increasing transformers. Voltage regulator circuits are generally used to stabilize the output voltage of the rectifier according to the amount of input from the transformer. However, components for high-voltage stabilizer circuits are rare, which becomes an obstacle to the stabilization of the rectifier output. This study aimed to determine the performance of the designed rectifier circuit against a non-center tap step-up direct current (DC) 400 V transformer and compare the measurement results to manual calculations. The research method is a direct comparison between the input and output voltage values of the transformer after going through a rectifier circuit. This experiment was conducted using the repeatability method three to five times for each voltage variation on the transformer. The voltage variations successfully created are 0 to 50, 0 to 100, 0 to 200, and 0 to 400 V. The output test results from the DC transformer and rectifier circuit show linear results and an increase in peak-to-peak voltage data between the transformer and rectifier outputs by 3.8%.

This paper presents the modeling of a full-wave rectifier circuit based on piezoelectric vibration transducer for energy-harvester system. Piezoelectric vibration crystals are a viable means of harvesting energy for low-power embedded systems e.g. wireless sensor network. Distinct power handling circuits are assessed with the presence of piezoelectric vibration based energy harvesting transducer. Inside the interface circuit, the voltage should be started up when the AC input voltage is very low to supply a regulated DC voltage up to 2V. An active technique is chosen to design an ultra-low power circuit from a piezoelectric vibration transducer. MOSFET bride ac–dc rectifier, energy storage device e.g. capacitor and boost converter with regulator are the common components of the energy harvesting circuits. An integrated promoter ac-dc rectifier circuit and boost converter that accept a maximum input voltage of 0.3V and provide a regulated output voltage of 2V serve as the supply. The MOSFET and thyristor are considered to develop the proposed circuit replacing conventional ac-dc rectifier due to low input voltage at which diode does not work.

Full textAbstract:
Parasitic oscillations in the rectifier diode voltage of phase-shifted-full-bridge (PSFB) converters limit their application in high-voltage and high-power situations. The conventional analysis method for parasitic oscillation in rectifier diode voltage in PSFB converters treats the filter inductor as a constant current source and fails to consider the impact of changes in filter inductor current on the rectifier diode’s parasitic oscillation. Consequently, this approach does not apply when analyzing the rectifier diode voltage’s parasitic oscillations in high-power PSFB converters employing an input-parallel output-series (IPOS) configuration with interleaved drive. This research paper introduces an innovative equivalent circuit model for analyzing the parasitic oscillations of rectifier diode voltage in IPOS high-power PSFB converters. The model takes into account the mutual influence of rectifier diode voltage oscillations between submodules under interleaved control, considering the influence of changes in filter inductor current on rectifier diode parasitic oscillation. Based on the circuit model, we explain the mechanism of multiple oscillations of the rectifier diode voltage and the reason for the high peak of the first oscillation. Consequently, the interplay of rectifier diode voltage oscillations in IPOS high-power k-module PSFB converters under interleaved control is analyzed. To mitigate the adverse effects of rectifier diode voltage parasitic oscillation, a buffering strategy involving the connection of a resistor capacitor diode (RCD) circuit in parallel after the rectifier bridge is adopted, considering the structure of the IPOS high-power PSFB converter. The study provides a detailed analysis of the circuit’s operation mechanism upon incorporating the RCD buffer circuit and establishes the relationship between buffer capacitance, resistance, and spike voltage. Furthermore, a design method for buffer capacitors and discharge resistors in buffer circuits is presented. Finally, a 100 kW prototype is tested to verify the rectifier diode voltage oscillation mechanism of the IPOS high-power PSFB converter and the rationality of the buffer capacitor and discharge resistor design method under the interleaved drive approach.

Radio Frequency (RF) energy harvesting is a process where RF energy from the ambient source is collected and converted into an electrical energy by using a rectifier circuit. However, the collected RF energy only supplies very low input power. Therefore, it is important to design a circuit that not only rectified the RF signal, but also with amplified characteristic to obtain a higher output voltage from a low input power. Driven by the increasing use of Internet of Things (IoT) devices operating in the 2.4 GHz Industrial, Scientific, and Medical (ISM) band, the presented rectifier circuit in this paper is designed in the same band as well. Initially, the voltage doubler circuit is chosen as the primary rectifier circuit, afterward cascaded into several stages until the most optimized result is obtained. The optimization is investigated across -30 dBm to 0 dBm of RF input power by varying the value of capacitor and resistor at a single stage. Based on the topology analysis, Dickson topology yields slightly higher voltage compared to Villard. In turn, the optimized number of stages is 6 because higher stages resulted to less output power. The measured reflection coefficient of the fabricated prototype is better than 40 dB at the center frequency with 240 MHz bandwidth. The rectified voltage is 3.4 V with 0 dBm input power. When it is supplied by 5 dBm input power, the green LED that connected to rectifier circuit output is light-up, confirming the RF energy harvesting application.

The voltage doubling rectifier circuit is the core component of the high voltage generator, so it is very important to study the stability of the voltage doubling rectifier circuit. Through the study of bidirectional rectifier circuit, double voltage rectifier circuit produces an output ripple and response time is superior than the basic voltage rectifier circuit. At the same time to study the bidirectional rectifier circuit is optimized, the capacity of the output arm greatly increases which leads to reduction in the output ripple, as the capacity reaches large enough value the output ripple approaches zero. Thus, greatly increasing the circuit in steady state time.

Introduction. The presence in low-voltage electrical networks of a significant number of electrical appliances with rectifiers determines a sufficiently high level of non-sinusoidality of currents and voltages. This significantly reduces the efficiency of both the network itself and individual consumers sensitive to the spectral composition of the supply voltage. At the same time, a significant part of electrical installations with a DC link requires elimination of ripples at the rectifier output, which, in turn, affects the nature of their power consumption. Goal. Study of dependence of the level of non-sinusoidality of currents consumed by the rectification circuit when feeding a linear load on the degree of voltage ripple smoothing at the rectifier output. Materials and methods. The study is based on the analysis of the spectral composition of the load currents with a rectifier bridge at different capacitance of the smoothing capacitor at the output of the rectifier. Results and discussion. The relationship between the capacitance value of the smoothing capacitor at the output of the bridge rectifier and the shape of the current consumed from the network is determined. A connection was revealed between the level of ripple of the rectified voltage and the degree of non-sinusoidality of the consumed currents. Conclusion. According to the results of the conducted research, it can be concluded that the non-sinusoidal character of power consumption of installations with DC link will be determined not only by the smoothing capacitor capacitance, but also by the load resistance at the output of the rectifier.

This paper discusses the design and simulation of the Cascade Greinacher circuit to increase the dc output voltage and current. The voltage increasing circuit using the Cockroft-Walton method has a large output voltage ripple and voltage drop. Meanwhile, half wave and full wave rectifier circuits are only capable of producing a DC output voltage and do not reach the maximum voltage value. In addition, the load resistance at each input power saturation is different and high frequencies require the addition of a capacitor circuit. Therefore, the Greinacher Doubler Circuit (GDC) rectifier is proposed with a modified diode and capacitor series arranged in nine levels in parallel. The circuit modification is used as a DC output voltage rectifier to reduce output voltage ripple. Then the circuit modification was tested by simulating the PSIM software and varying input voltages. Simulation testing uses a 220 volts voltage source, 50 Hz frequency, and component specifications for a single-phase step-down transformer 220 to 12 volts, 8 diodes (DXN, DN/DXN1, DN1/DXN2, DN2/DXN3, DN3), 8 capacitors with 4700Uf value (CXN, CN/CXN1, CN1/CXN2, CN2/CXN3, CN2), and 100 Ω resistor. simulation results which produce a voltage greater than 3 times the input voltage, namely 35.7 V and a current of 0.98 A. Even though at times 0.001 seconds and 0.0035 seconds and 0.0054 seconds the output voltage and current are constant at 4.9 volts respectively, the current is 0.03 A, current 0.08 A and current 0.013 A. The output voltage Vout, Vs and current continue to increase when it reaches 1 second.

At the present stage of industrial production in China, rectifier circuits still have an important position, and their safe, reliable, and efficient operation is still a necessary issue to be explored in the development of power electronics technology. Therefore, this paper will build an improved three-phase bridge rectifier circuit based on the traditional three-phase bridge fully controlled rectifier circuit, replacing the thyristor with an insulated gate bipolar transistor (IGBT) under the same basic principle, so that it can be more easily controlled by industrial intelligence. The PID controller is introduced to make the output voltage of the rectifier circuit gradually converge to a certain value by continuously correcting the calculation of the trigger angle α and the calculation of the voltage and current values. The simulation results show that the PI-controlled three-phase bridge fully controlled rectifier circuit model established in the paper makes the output of the circuit eventually stabilize under the influence of the closed-loop control, and the simulation results reach the expected value and show strong robust stability. For industrial applications, improving the safety, reliability, efficiency, and flexibility of bridge rectifier circuits is of good reference in practical engineering applications.

The circuit achieves 38% power conversion efficiency at 920 MHz, -21 dBm input power, and 1M DC output load. The -21 dBm threshold power improves efficiency and reduces total power consumption, which extends the communication range. The short operating distance of RFID technology has limited its application range in other fields. The theoretical equations and design techniques of the proposed regulated voltage supply circuit are presented and validated with simulation results in a 90 nm CMOS process.

<em>Direct current (DC) motors are used in variable-speed drives to produce a high starting torque, and provide speed control over a wide range of speed. Controlled rectifiers are popularly employed in the speed control of DC motors. In this paper, the speed control of separately excited dc motor, using single-phase, full-wave, fully-controlled rectifier was investigated. Controlled rectifiers were used to produce variable DC output voltages from a fixed alternating current (AC) voltage. Since the armature voltage (V<sub>a</sub>) of a DC motor is the output of a single-phase controlled rectifier, it was varied by varying the delay or firing angle (α<sub>a</sub>) of the rectifier. The field circuit also requires a rectifier to control the field current (I<sub>f</sub>) or flux by varying the firing angle (α<sub>f</sub>). In this paper, the motor speed equations were derived. The output equations of the rectifiers were also derived and incorporated into the motor speed equations. The graphs generated from these equations show clearly how the speed of the DC motor varies with the output voltage or current of the controlled rectifiers. Thus, motor speed, being a function of the armature voltage (V<sub>a</sub>), or the field current (I<sub>f</sub>) was controlled. This paper demonstrates the control strategies of a separately excited dc motor, using single-phase controlled rectifiers</em><em>.</em>

The article discusses the problem of transformation of measuring signal of differential transformer converter of universal testing machines for further processing by microprocessor controller. In order to automate the testing process, it is necessary to collect, process and transmit the measured data to an automated workplace using a microprocessor controller. Due to the fact that usually the secondary windings of the differential transformer converters produce an alternating voltage of very small magnitude, such a measurement signal cannot be processed with the help of modern microprocessor controllers without conversion. Since the analog-to-digital converter of the microprocessor controller cannot operate with alternating voltage, it becomes necessary to rectify and amplify the measuring signal. For low voltages (less than 0.6 V), the use of conventional resistor-diode rectifiers becomes impossible and there is a need for other methods of rectifying alternating current. It is proposed to use full-wave active rectifiers without diodes on operational amplifiers for conversion of the measuring signal of differential transformer converters, the main disadvantages of diode rectifiers and advantages of rectifiers on operational amplifiers are considered. The biggest advantage of a rectifier proposed for use in an automated testing system is the ability to simultaneously rectify and amplify the measurement signal with the required precision, allowing it to be processed by most modern microprocessor controllers. For the first time, an automated testing system on a tensile machine was developed using an active full-wave voltage rectifier on operational amplifiers without the use of diodes. The circuit shown in the article makes it possible to convert the signal of a differential transformer converter for further processing using the Arduino microcontroller platform. An amplifying active full-wave voltage rectifier without diodes on operational amplifiers can be used to modernize testing or measurement equipment containing a differential transformer transducer of a measuring signal. The developed electrical circuit of the rectifier was applied to automate the process of testing on the breaking machine of model P-0.5. Keywords: differential transformer converter, operational amplifier, rectifier, measuring signal converter, tensile testing machine, automated test system.

Full textAbstract:
The LLC resonant converter is widely recognized as an effective solution for achieving high efficiency in high-frequency operations. This is primarily due to its ability to perform zero-voltage switching (ZVS) on primary switches and zero-current switching (ZCS) on secondary rectifier switches. However, implementing the secondary rectifier of an LLC resonant converter often requires the use of jumpers on the PCB to construct circuit topologies such as the center-tap rectifier (CTR), full-bridge rectifier, and voltage-doubler rectifier (VDR). In conventional VDR configurations, the source voltage of the high-side FET fluctuates according to the switching operation of the primary switch. This fluctuation necessitates auxiliary windings or bootstrap circuits to provide a floating voltage source, adding significant complexity to gate drive circuits in high-power-density applications. This complexity poses a major barrier to the practical adoption of VDRs. To address these challenges, this paper proposes a novel rectification circuit based on the VDR topology, specifically designed for LLC resonant converters, offering simplified gate drive circuitry and improved suitability for high-power-density applications.

Full textAbstract:
The series-type 12-pulse rectifier generates a large amount of harmonics in the AC side current due to the strong nonlinearity of its rectifying diodes, causing serious harmonic pollution to the power grid. This article proposes a series 36-pulse rectifier based on a DC side dual passive frequency-doubling circuit to suppress the AC side current harmonics of a 12-pulse rectifier. The rectifier uses two symmetrical passive pulse multiplication circuits to regulate the circulation in the DC side circuit, increasing the output voltage and current state of the rectifier bridge, thereby increasing the number of pulses in the rectifier from 12 times to 36 times. Firstly, the working principle of the rectifier and the working mode of the dual passive frequency-doubling circuit were analyzed. Secondly, the harmonic suppression mechanism of the rectifier input current was revealed, and the frequency-doubling characteristics of the load voltage were analyzed. Finally, the correctness of the theoretical analysis was verified through a semi-physical platform. The verification and comparison results show that under the optimal conditions of the injecting transformer turns ratio, the DPPC can not only reduce the THD value of the input current by about 1/3 (from 14.87% to 4.78%) but can also increase the fluctuation frequency of the load voltage by 3 times (from 12 to 36), while improving the power quality of the AC/DC side rectifier and achieving the low harmonic operation of the rectifier. The proposed 36-pulse rectifier can effectively suppress harmonics; it has the advantages of simple structure, strong robustness, and high output voltage gain, and it is suitable for medium-voltage and high-voltage high-power rectification applications.

Full textAbstract:
In this paper, a direct current (dc) converter with the abilities of bidirectional power transfer and soft switching characteristics is studied and implemented. The circuit schematic of the developed dc converter is built by a half-bridge converter and a center-tapped rectifier with synchronous rectifier. Under forward power transfer, a half-bridge circuit is controlled to regulate the low-voltage side at a stable value. For backward power transfer, a center-tapped rectifier with synchronous rectifier is regulated to control the high-voltage side at the desired voltage value, and the half-bridge circuit is operated as a voltage doubler rectifier. Active power devices are operated at zero-voltage switching using a series resonant technique on the high-voltage side with frequency modulation and inductive load operation. The practicability of the developed converter is established from experiments with a laboratory prototype circuit.

AbstractA novel, dual-band, voltage-multiplying (RF-DC) rectifier circuit with load-tuned stages resulting in a 50 Ω input-impedance and high RF-DC conversion in 2.4 and 5.8 GHz bands for wireless energy-harvesting is presented. Its novelty is in the use of optimal-length transmission lines on the load side of the 4 half-wave rectifying stages within the two-stage voltage multiplier topology. Doing so boosts the rectifier's output voltage due to an induced standing-wave peak at each diode's input, and gives the rectifier a 50 Ω input-impedance without an external-matching-network in the 2.4 GHz band. Comparisons with other rectifiers show the proposed design achieving a higher DC output and better immunity to changing output loads for similar input power levels and load conditions. The second novelty of this rectifier is a tuned secondary feed that connects the rectifier's input to its second stage to give dual-band performance in the 5.8 GHz band. By tuning this feed such that the second stage and first stage reactances cancel, return-loss resonance in the 5.8 GHz band is achieved in addition to 2.4 GHz. Simulations and measurements of the design show RF-DC sensitivity of −7.2 and −3.7 dBm for 1.8V DC output, and better than 10 dB return-loss, in 2.4 and 5.8 GHz bands without requiring an external-matching-network.

Full textAbstract:
This paper describes an improved non-linear switching circuit (INLSC) for active rectification of voltage and reduction of ripples in the voltage waveform for the piezoelectric energy harvesting (PEH) system. The proposed converter controls the alternating current (AC) generated by the piezoelectric device (PD) under mechanical vibration. The proposed circuit combines the boost and buck-boost processes through a switching process, which functions in both positive and negative cycles. In addition, it controls the voltage and frequency of the load capacitor. In this process, the passive components in the circuit are energised by being short with the AC voltage using switching signals, which facilitates the active rectification of ultra-low AC voltage. Design considerations, theoretical analysis, simulations and experimental results are presented. It was shown that the circuit was able to control the switching signal and to convert low AC voltage (0.44 Vi) to high direct current (DC) voltage (6.5 Vdc) while achieving an output power of 469 µW which outperforms the existing similar circuits and synchronous rectifier circuit. The ripples in the rectified voltage were also comparatively less. Application-wise, the proposed circuit could power a manually connected 7-segments display, commonly used for traffic applications.

In this study, The fabrication of a p-n junction NiO/Ga2O3 rectifier in which we employ a bilayer NiO structure with two different doping levels to achieve both high breakdown voltage and low on-state resistance was described. The band alignment of the NiO to the Ga2O3 was measured. Selective wet and dry etch processes for removing NiO from the underlying Ga2O3 was developed. Finally, the dc and switching performance of the rectifiers was characterized. The maximum breakdown voltage was 2.7 kV for a 1 mm diameter rectifier, with 2.5 A forward current and on/off ratio > 108 over a broad range of switching voltages. The reverse recovery time was limited by the measurement circuit but was < 100 µs. These results show the promise of heterojunction rectifiers based on Ga2O3 for future generations of power switching applications. Figure 1

A milling process utilize DC motors and rectifier circuits. Semiconductor components in the rectifier circuit could cause harmonic distortion. At PT X, the voltage THD generated at the 6KV feeder panel has exceeded the standards set by the IEEE. This study aims to analyze the voltage THD caused by a controlled rectifier circuit and DC motors, and to design a filter to mitigate it. MATLAB software is used to analyze the THD voltage. From the simulation results, it is known that the 400KW, 450KW, and 600KW DC motors produce voltage THD values of 9.35%, 14.23%, and 12.28% respectively which exceed the set standards of 8%. A single-tuned passive filter is designed to reduce the THD voltage value on each motor. The installation of the filter effectively reduces the THD voltage value in the 400KW, 450KW, and 600KW DC motors to 4.34%, 5.38%, and 6.35% respectively.

On-chip systems are challenging owing to the limited size of the components, such as the capacitor bank in the rectifier. With a small on-chip capacitor, the output voltage of the rectifier might ring if the circuit experiences significant changes in current. The reference circuit is the first block after the rectifier, and the entire system relies on its robustness. A fully integrated dual-voltage reference circuit for bio-implantable applications is presented. The proposed circuit utilizes nonlinear current compensation techniques that significantly decrease supply variations and reject high-supply ripples for various frequencies.

This paper designs a new type of rectifier voltage-multiplier circuit named MR_MOS circuit. It uses a low let-through resistance MOS tube to replace the conventional rectifier diode, and adds the voltage-multiplying factor to the synchronous input port. Therefore, it can improve the rectifier effect and increase the output voltage. By the simulation result of Synopsys Saber Platform, it shows that the new type circuit can implement the rectification and voltage-multiplying by the simulating output pulse voltage of nanofiber made in Deakin University as the source of excitation.

In this paper, a low-power, single-stage, active rectifier based on a new charge-pump circuit is presented to be used in biomedical implants. The proposed circuit not only rectifies the AC input voltage to a DC voltage but also amplifies the DC output voltage to a higher level. Low-loss MOS switches are used in the structure of the designed circuit to provide high power conversion efficiency. In addition, by using two comparators, the reverse leakage current is somehow eliminated, resulting in a higher increase in the power efficiency. By tying the source and bulk terminals of the utilized transistors, the body effect problem has been solved, and by connecting the p-substrate to the ground, which is the lowest voltage in the circuit, the latch-up phenomenon is eliminated without any extra circuit. The proposed rectifier is implemented and post-layout simulated in a 0.18 µm standard CMOS technology. According to the simulation results, 1.205 V output DC voltage is achieved from an AC input signal with the peak-to-peak amplitude of 1 V at the operating frequency of 13.56 MHz with a 3 kΩ load resistance. The total active area of the designed circuit is 0.167 mm2 with a maximum power conversion efficiency of 98.2%, output power in the range of 0.5–1.5 mW, and voltage conversion ratio of 120%.

Abstract The voltage balance of the series diodes is the premise to ensure the stable and reliable operation of the high voltage uncontrolled rectifier valve. When traditional RC and RCD voltage balancing methods are applied to high voltage uncontrolled rectifier valves in far-reaching offshore wind farms, the complex and changeable operating environment poses a challenge to the anti-interference of the balance effect of the snubber circuit. In this paper, an active RCD adaptive voltage balancing control strategy with strong anti-interference ability is proposed based on the establishment of the active RCD voltage balancing model of the high voltage uncontrolled rectifier valve. The parameter tuning method of the active RCD snubber circuit is given, and the auto-PID control strategy of the active RCD snubber circuit is proposed according to its nonlinear time-varying characteristics. The simulation example verifies that the active RCD adaptive voltage balancing strategy of the high voltage uncontrolled rectifier valve has strong anti-interference performance, which provides a reference for the design of the high voltage uncontrolled rectifier valve voltage sharing system in the far-reaching offshore wind farm.

In order to improve the reliability of a more sustainable mobility generator, a four-phase Doubly Salient Electro-Magnetic Generator (DSEG) and its phase-isolated rectifier are proposed in this paper. The mathematical model of the machine and fault-tolerant rectifiers is proposed, which indicates that the four-phase fault-tolerant DSEG should have symmetric phases. With the asymmetry analysis of the traditional 8/6-pole DSEG, a new 12/9-pole DSEG with symmetric phases is proposed.

Rectifiers are becoming more prevalent in a wide range of applications, including power supplies for microelectronics, household electrical devices, battery charging, and power conversion in high-voltage direct current (HVDC) transmission systems. Conventional rectifiers often employ uncontrolled diodes, which have the drawback of generating a fixed output voltage that cannot be modified. There is a requirement for a regulated rectifier, specifically a three-phase PWM Rectifier that transforms AC voltage into DC voltage with an output voltage that surpasses the input voltage and can be modified as per requirements. This study explores the comparison between s-domain and z-domain PI controller designs in the context of controlling a three-phase pulse width modulation (PWM) rectifier. Applying the dual-closed-loop control technique with the pole-zero cancellation approach, we can calculate the PI parameters for controlling the current and voltage in the circuit. The values of the parameters are as follows: K_pc = 4, K_ic = 100, K_pv = 0.097, and K_iv = 4.85. Applying the forward Euler method to transform the PI controller from the s domain to the z domain. The test results for the PWM Rectifier PI controller were conducted in both the s-domain and z-domain. As per the setpoint, a three-phase voltage source with a value of 220 Volts was used, resulting in a stable DC voltage output of 600 Volts.

For a conventional monolithic piezoelectric transducer (PT) using a full-bridge rectifier, there is a threshold voltage that the open-circuit voltage measured across the PT must attain prior to any transfer of energy to the storage capacitor at the output of the rectifier. This threshold voltage usually depends on the voltage of the storage capacitor and the forward voltage drop of diodes. This article presents a scheme of splitting the electrode of a monolithic piezoelectric vibration energy harvester into multiple ( n) equal regions connected in series in order to provide a wider operating voltage range and higher output power while using a full-bridge rectifier as the interface circuit. The performance of different series stage numbers has been theoretically studied and experimentally validated. The number of series stages ([Formula: see text]) can be predefined for a particular implementation, which depends on the specified operating conditions, to achieve optimal performance. This enables the system to attain comparable performance compared to active interface circuits under an increased input range while no additional active circuits are required and the system is comparatively less affected by synchronized switching damping effect.

This paper presents a resonant converter with the benefits of wide output voltage, wide soft switching characteristics for power devices and high circuit efficiency. Since the series resonant circuit is adopted on the primary side, the power switches are turned on under zero voltage switching and power diodes on the secondary side can be turned off under zero current switching. To overcome the drawback of narrow voltage operation range in the conventional resonant converter, full-bridge rectifier and voltage-doubler rectifier topologies are employed on the secondary side for low-voltage output and high-voltage output applications. Therefore, the voltage rating of power devices on the secondary side is clamped at output voltage, rather than two times output voltage, in the center-tapped rectifier circuit. Synchronous power switches are used on the secondary side to further reduce the conduction losses so that the circuit efficiency can be further improved. To verify the theoretical analysis and circuit performance, a laboratory prototype with 1 kW rated power was built and tested.

Regulating LED current and voltage is critical to maintaining a constant luminous flux in AC- or DC-powered LED lighting circuits. Today, users require constant current drivers that can provide a wide range of output voltages to drive different numbers of series-connected LED arrays. This work proposes an LED driver by combining an isolated SEPIC converter operating in the continuous conduction mode (CCM) and a modified Vienna rectifier. The proposed LED driver offers a single-switch control structure by adding a Vienna rectifier to the integrated SEPIC-FLYBACK converter. This driver structure provides many advantages over traditional bridge rectifier structures. The prototype circuit was tested in an 18 W continuous current mode (CCM) to verify its feasibility. As a result of the values obtained from both simulation and prototype circuit models, it has been shown to provide many of the following advantages: 95% high efficiency, high reliability, 4% low total harmonic distortion, 97% high power factor, and 70 V low switching voltage. This work meets class C 3-2 and IEC 61000 standards.

To reduce the current harmonics on the input side of a multi-pulse rectifier, this paper proposes a low harmonic current source series multi-pulse rectifier based on an auxiliary passive injection circuit at the DC side. The rectifier only needs to add an auxiliary passive injection circuit on the DC side of the series 12-pulse rectifier, which can change its AC input voltage from 12-step waves to 24-step waves. We analyzed the working mode of the rectifier, optimized the optimal turn ratio of the injection transformer from the perspective of minimizing the total harmonic distortion (THD) value of the input voltage on the AC side, and analyzed the diode open circuit fault in the auxiliary passive injection circuit. Test verification shows that, after using the passive harmonic injection circuit, the THD value of the input voltage of the AC side of the rectifier is reduced from 14.03% to 4.86%. The THD value of the input current is reduced from 5.30% to 2.16%. The input power factor has been increased from 98.86% to 99.83%, and the power quality has been improved.

Full textAbstract:
Power conversion efficiency (PCE) has been one of the key concerns for power management circuits (PMC) due to the low output power of the vibrational energy harvesters. This work reports a dynamic threshold cancellation technique for a high-power conversion efficiency CMOS rectifier. The proposed rectifier consists of two stages, one passive stage with a negative voltage converter, and another stage with an active diode controlled by a threshold cancellation circuit. The former stage conducts the signal full-wave rectification with a voltage drop of 1 mV, whereas the latter reduces the reverse leakage current, consequently enhancing the output power delivered to the ohmic load. As a result, the rectifier can achieve a voltage and power conversion efficiency of over 99% and 90%, respectively, for an input voltage of 0.45 V and for low ohmic loads. The proposed circuit is designed in a standard 130 nm CMOS process and works for an operating frequency range from 800 Hz to 51.2 kHz, which is promising for practical applications.

Full textAbstract:
A novel 10-Watt-Level high-power microwave rectifier with an inverse Class-F harmonic network for microwave power transmission (MPT) is presented in this paper. The high-power microwave rectifier circuit comprises four sub-rectifier circuits, a 1 × 4 power divider, and a parallel-series dc synthesis network. The simple inverse Class-F harmonic control network serves dual roles: harmonic control and impedance matching. The 1 × 4 power divider increases the RF input power fourfold, reaching 40 dBm (10 W). The parallel-series dc synthesis network enhances the resistance to load variation. The high-power rectifier circuit is simulated, fabricated, and measured. The measurement results demonstrate that the rectifier circuit can reach a maximum RF input power of 10 W at 2.45 GHz, with a maximum rectifier efficiency of 61.1% and an output dc voltage of 23.9 V, which has a large application potential in MPT.

Full textAbstract:
This paper models and analyzes the Complementary Metal Oxide Semiconductor (CMOS) cross-coupled differential-drive (CCDD) rectifier for Ultra-Low-Power ambient radio-frequency energy harvesters (RFEHs) working in the subthreshold region. In this paper, two closed-form equations of CCDD rectifier output voltage and input resistance in the subthreshold region were derived based on BSIM4 models of NMOS and PMOS. The model give insight to specify circuit parameters according to different inputs, transistor sizes, threshold voltages, numbers of stages, load conditions and compensation voltages, which can be used to optimize the rectifier circuit. There is a good agreement between the simulation results and these models, and these models have a maximum deviation of 10% in comparison with the simulation results in the subthreshold region. The measurement results of a single-stage CCDD rectifier reported in a previous paper were adopted to verify the model. The output voltage and input resistance predicted by these models provide excellent consistency with corresponding measurement results. The model can be employed to optimize the CCDD rectifier without expensive calculation in the design stage.
