Abstract:

Developments in automotive (particularly hybrid-electric vehicles), aerospace, and energy production industries have led to expanding research interest in integrated circuit (IC) design toward high-temperature applications. A high-voltage, high-temperature silicon-on-insulator (SOI) process allows for circuit design to expand into these extreme environment applications. Nearly all electronic devices require a reliable supply voltage capable of operating under various supply voltages and load currents. These supply voltages and load currents can be either DC or time-varying signals. In this work, a stable supply voltage for embedded circuits is generated on chip via a voltage regulator producing a stable 5-V output voltage. Although applications of this voltage regulator are not limited to gate driver circuits, this regulator has been developed to meet the demands of a gate driver IC. The voltage regulator must be able to provide reliable output voltage over an input range from 10 V to 30 V, a temperature range of −25°C to 200°C, and output loads from 0 mA to 200 mA. Additionally, low power stand-by operation is provided to help reduce heat generation resulting in lower operating junction temperature. The designed voltage regulator has been successfully tested from −50°C to 200°C while demonstrating an output voltage variation of less than 10 mV under the full range of input voltage. Additionally, line regulation tests from 10 V to 30 V show a 12-ppm/V supply sensitivity. Full temperature and input voltage range tests reveal that the no-load supply current draw is within 17 mA while still providing in excess of 200-mA load current upon demand. Modifications to the existing design or off-chip biasing can widen the range of attainable output voltages and drive capabilities.

Abstract:

This paper presents a 5 V-to-3.3 V linear regulator circuit, which uses 3.3 V CMOS transistors to replace the 5 V CMOS transistors. Thus, the complexity of the manufacturing semiconductor process can be improved. The proposed linear regulator is implemented by cascode architecture, which requires three different reference voltages as the bias voltages of its circuit. Thus, the three-output temperature-independent reference voltage circuit is proposed, which provides three accurate reference voltages simultaneously. The three-output temperature-independent reference voltages also can be used in other circuits of the chip. By using the proposed temperature-independent reference voltages, the proposed linear regulator can provide an accurate output voltage, and it is suitable for low cost, small size, and highly integrated system-on-chip (SoC) applications. Moreover, the proposed linear regulator uses the cascode technique, which improves both the gain performance and the isolation performance. Therefore, the proposed linear regulator has a good performance in reference voltage to output voltage isolation. The voltage variation of the linear regulator is less than 2.153% in the temperature range of −40°C–120°C, and the power supply rejection ratio (PSRR) is less than −42.8 dB at 60 Hz. The regulator can support 0~200 mA output current. The core area is less than 0.16 mm2.

Abstract:

Abstract. This paper presents two high-voltage circuits used in power management, a switching driver for buck converter with optimized on-resistance and a low dropout (LDO) voltage regulator with 2-stacked pMOS pass devices. The circuit design is based on stacked MOSFETs, thus the circuits are technology independent. High-voltage drivers with stacked devices suffer from slow switching characteristics. In this paper, a new concept to adjust gate voltages of stacked transistors is introduced for reduction of on-resistance. According to the theory, a circuit is proposed that drives 2 stacked transistors of a driver. Simulation results show a reduction of the on-resistance between 27 and 86 % and a reduction of rise and fall times between 16 and 83 % with a load capacitance of 150 pF at various supply voltages, compared to previous work. The concept can be applied to each high-voltage driver that is based on a number (N) of stacked transistors. The high voltage compatibility of the low drop-out voltage regulator (LDO) is established by a 2-stacked pMOS transistors as pass device controlled by two regulators: an error amplifier and a 2nd amplifier adjusting the division of the voltages between the two pass transistors. A high GBW and good DC accuracy in line and load regulation is achieved by using 3-stage error amplifiers. To improve stability, two feedback loops are utilized. In this paper, the 2.5 V I/O transistors of the TSMC 65 nm CMOS technology are used for the circuit design.

Abstract:

The voltage sag problem in a power grid can be solved by a voltage regulator. In this study, the voltage regulator based on thyristor was used to compensate the single-phase and three-phase voltage of voltage sag fault, so as to recover the normal level of voltage. The simulation analysis was carried out on MATLAB. The results showed that voltage sag faults mainly affected the amplitude of voltage, but not the frequency of voltage. After voltage regulation, the single-phase and three-phase voltage waveforms in the fault period had a certain recovery, but the voltage regulator had a certain hysteresis effect.

Abstract:

Voltage regulator is designed to automatically maintain the constant of regular voltage level. Every automotive IC has its own regulator module for analog and logic circuit power supply. The output load regulation and current consumption are directly related to the IC’s performance, or even the whole application module. The performance of regulator is not only related with the output parameters, but also the protection character. The over voltage protection feature guarantees the IC’s working environment within specific voltage input range. This article use one IDC’s (Intelligent Distribution Controller) regulator module to describe the design theory for regulator over voltage performance improvement. The test investigation and verification on ATE (Automatic Test Equipment) are demonstrated. The parameter of over voltage threshold is optimized obviously by 2% yield increasing.

Abstract:

Hybrid Excitation Doubly Salient Generator (HEDSG) with parallel magnetic circuits is performed in this paper, and the main flux in the machine is determined by the permanent magnet and the field coils. The structure and working principle of the generator are described in detail. In order to build the voltage regulation system of HEDSG, a bidirectional excitation voltage regulator is proposed, which could keep the output voltage of the generator stable by adjusting the field current. The two control loops including excitation current feed-forward and output voltage feedback loops are applied in the voltage regulator. Subsequently, the mathematical model of the voltage regulation system is constructed after the transfer function of the generator is obtained by using system identification method. Moreover, in order to realize the field current bidirectional flow, bipolar pulse width modulation is also applied in the regulator, and the control parameters influencing on the output voltage are analyzed. Lastly, the prototype of bidirectional excitation voltage regulator is designed and theoretical analysis and simulation results are verified by the stable and dynamic experiments.

Abstract:

Output voltage regulation is an essential technology for achieving stable wireless power supply. A receiver-side switching voltage regulator is useful for realizing output voltage regulation. However, this paper shows that the switching voltage regulator degrades the transfer efficiency to below 50% in a wireless power transfer system that consists of a class-D power inverter and series-resonant transmitting and receiving resonators. Such efficiency degradation is caused by the instability of an operating point where the efficiency is >50%. The input resistance value of the switching voltage regulator at a stable operating point is much higher than the optimum value for maximizing the efficiency. To stabilize the high-efficiency operating points, this paper formulates a stability condition and derives its sufficient condition. The sufficient condition facilitates a system design method using a K-impedance inverter that allows for the optimum input resistance value to lie in the range of allowable input resistance values. In addition, we introduce an input-voltage-based efficiency maximization method for the system with the receiver-side switching voltage regulator. By combining these two methods, efficiency maximization is realized with the receiver-side switching voltage regulator. The proposed methods were verified by both simulations and measurements.

Abstract:

This work presents a bandgap voltage reference (BGR) integrated in 0.25-μm bipolar-CMOS-DMOS (BCD) technology. The BGR circuit generates a reference voltage of 1.22 V. It is able to withstand large supply voltage variations of vehicle applications from 4.5 V, e.g., in case of cranking, up to 60-V, maximum value in case of emerging 48-V battery systems for hybrid and electrical vehicles. The circuit has an embedded high-voltage (HV) pseudo-regulator block that provides a more stable internal supply rail for a cascaded low-voltage bandgap core. HV MOS are used only in the pre-regulator block thus allowing the design of a BGR with compact size. The proposed architecture permits to withstand large input voltage variations with a temperature drift of a hundred of ppm/°C, a line regulation (LR) of few mV/V versus the external supply voltage and a power supply rejection ratio (PSRR) higher than 90 dB.

Abstract:

Although there currently exists a wide range of voltage regulators that are commercially available, the search for devices with a simpler physical design remains the focus of research studies. Following this line, an electromagnetic voltage regulator (EVR) arrangement has been proposed. The EVR is constituted of an autotransformer that supplies, via discrete taps, a series transformer that injects voltage for regulating the feeder voltage. Even though its operating principle is shown as being similar to that of other devices on the market, the physical arrangement and operating strategy of EVR show novelties which result in properties such as: economic attractiveness, constructive simplicity, and operational reliability. Moreover, when installing voltage regulators, efficacy studies must be carried out to optimize equipment design. In this context, this paper aims at evaluating the factors that influence the effectiveness of the EVR in restoring voltage variations according to the determinations imposed by regulatory agencies. The ultimate goal of this study is to determine the voltage deviation range that the EVR is able to restore. To achieve this goal, a mathematical modeling of the EVR is given and study cases are computationally carried out to investigate its performance when connected to a typical distribution feeder.

Abstract:

The article is devoted to the thyristor voltage regulator (TVR) development. The TVR purpose is to control power flows and regulate voltage in 6-20 kV distribution electrical networks (DEN). The principle of TVR operation is based on the plus EMF (or minus EMF) introduction into power line when the shared use of longitudinal (change of magnitude) and transverse (change of phase) voltage regulation. The description of the TVR prototype is given. The TVR prototype consists of a 0.4 kV thyristor switches, power transformers (shunt and serial) and a 6 kV switchgear. The TVR has a two-level control system (CS). The TVR prototype experimental research was conducted in four stages: check of power equipment, first level CS research, second level CS research, prototype tests as a whole. The connection diagrams (thyristor switches unit, transformer and measuring equipment) and contact connections reliability were checked when the power part was tested. A qualitative characteristic of the input and output signals was obtained when testing the first level CS. It is found that the thyristor control pulses are formed according to the developed algorithm. The correctness of control system algorithms, executed and transmitted commands, passed and received data was confirmed as a result of the second level CS tests. The TVR research results indicate that the prototype provides the smoothness and specified accuracy of voltage regulation in all modes. The control range of the output voltage relative to the input was ±10%. The discreteness of regulation did not exceed 1.5%. The range of change in the shift angle of the output voltage relative to the input was ±5°. Research confirmed the TVR ES operability and its readiness for trial operation.

Abstract:

Dynamic Voltage Scaling is performed on automotive micro-controller AURIX from Infineon Technologies. In this micro-controller the core and different IPs operate on the 1.25 V supply rail, so dynamically voltage is changed according to the workload in the micro-controller. DVS is done either using an internal onboard voltage regulator or an external voltage regulator. An External board (KITPF3000FRDMEV), which has a controller and a Power Management Integrated Circuit (PMIC) is used for changing the supply voltage to the micro-controller during DVS using an external voltage regulator. The micro-controller is predicting the workload and according to workload, the control command is sent to the controller (FRDM-KL25) in the kit through I2C communication and then the controller sends the command to adjust the voltage of PMIC (PF3000) through I2C communication. Both current measurements for the internal voltage regulator and external voltage regulator are measured for various loads and latency is measured for various baud rates while using external voltage regulator through I2C protocol.

Abstract:

The Single-phase AC Regulator on Base of Bidirectional IGBT SwitchesIn the work one of the methods for regulation of sinus shape AC voltage for middle-power loads with activeinductive character is observed. Such a regulator keeping output voltage of sinus shape must be fast-reacting and work in closed-loop system. It's shown, that for providing such features Buck and Boost pulse regulators can be applied. The only difference from DC pulse converters is that electronic switches in the system must be with bidirectional conductivity. For this reason an IGBT transistors can be applied with implemented in structure reverse diodes and if such two transistors are connected in series and with contrary conductivity then at activating both one of them will be in on-state. Realization of AC regulators with such switches is described in the work. Results of computer modeling also are given. Output voltage ripples are investigated on subject of their range and efficiency of filtering equipment on LC base. Such regulators can be applied for instance in electrical transport self supply systems.

The implemented LDO regulator has a dropout voltage of 0.22 V and a maximum load current of 20 mA. It can also provide an output voltage of 0.98 V at a range of 1–1.3 V of the input voltage. The load regulation is 2.3 mV/mA while the line regulation is 0.05 V/V. The circuit consumes 385 μA with an input voltage of 1.2 V. The total area without pads is 0.092 mm2.

Abstract:

The work presented in this article is a contribution to the problem of controlling reactive powers and voltages in an electrical network. Among these control tools, the static reactive power compensator (SVC) was chosen because of its simplicity of control. SVC is one of the Alternative Flexible Current Transmission Systems (FACTS) devices which help to solve the problems encountered in the operation of electrical networks, either on the distribution side or on the transport side. To increase its compensation efficiency in the face of harmonic currents which cause voltage distortion, we have introduced a three-phase harmonic filter. This new hybrid SVC is used to control the reactive power, the voltage and in addition to reduce the voltage distortion and the correction of the power factor in the electrical energy transport network. In order to improve its efficiency, two voltage regulation systems have been chosen in the control system for this compensator, the fuzzy PI regulator and the PIP regulator.

Abstract:

This paper proposes a comparison between two methods of voltage regulation of over sending-end voltage in case of the load located near a substation. The first method is using tab change of power transformer and the other is the installation of voltage regulator in a factory. In the process, voltage level is completely measured before and after the installation of techniques, and is slightly decreased until it approaches to the lowest demand of loads, which can normally operate in the plant. The sequent test results show that the first method, sending-end voltage control via voltage regulator, can reduce squandered energy up to 8.3%, can also save energy up to 6.8% which is higher than the result of adjusting power transformer tap.

Abstract:

High power alternating voltage regulators commonly use few isolation transformers to compensate the variation of the input voltage or output load, and use a bidirectional-thyistor bridge with multiple arms to adjust the direction and magnitude of the compensation voltage . This kind of voltage regulator has been widely used for its simplicity, low cost, and high efficiency. But its compensation voltage adjustment process often accompanies with deep output voltage sags or high input current overshoots. An improved topology is proposed---adding one more circuit unit to help the adjustment of compensation voltage. The improved topology can adjust the compensation voltage smoothly---having neither output voltage sags nor input current overshoots.

Abstract:

This paper proposes a capacitor-less LDO with improved steady-state response and reduced transient overshoots and undershoots. The novelty in this approach is that the regulation is improved to a greater extent by the improved error amplifier in addition to improved transient response against five vital process corners. Also entire quiescent current required is kept below 100 . This LDO voltage regulator provides a constant 1.2 V output voltage against all load currents from zero to 50 mA with a maximum voltage drop of 200 mV. It is designed and tested using Spectre, targeted to be fabricated on UMC 180 nm.

Abstract:

When excised inside-out membrane patches are bathed in symmetrical Cl−-rich solutions, the current-voltage (I-V) relationship of macroscopic cystic fibrosis transmembrane conductance regulator (CFTR) Cl− currents inwardly rectifies at large positive voltages. To investigate the mechanism of inward rectification, we studied CFTR Cl− channels in excised inside-out membrane patches from cells expressing wild-type human and murine CFTR using voltage-ramp and -step protocols. Using a voltage-ramp protocol, the magnitude of human CFTR Cl− current at +100 mV was 74 ± 2% (n = 10) of that at −100 mV. This rectification of macroscopic CFTR Cl− current was reproduced in full by ensemble currents generated by averaging single-channel currents elicited by an identical voltage-ramp protocol. However, using a voltage-step protocol the single-channel current amplitude (i) of human CFTR at +100 mV was 88 ± 2% (n = 10) of that at −100 mV. Based on these data, we hypothesized that voltage might alter the gating behavior of human CFTR. Using linear three-state kinetic schemes, we demonstrated that voltage has marked effects on channel gating. Membrane depolarization decreased both the duration of bursts and the interburst interval, but increased the duration of gaps within bursts. However, because the voltage dependencies of the different rate constants were in opposite directions, voltage was without large effect on the open probability (Po) of human CFTR. In contrast, the Po of murine CFTR was decreased markedly at positive voltages, suggesting that the rectification of murine CFTR is stronger than that of human CFTR. We conclude that inward rectification of CFTR is caused by a reduction in i and changes in gating kinetics. We suggest that inward rectification is an intrinsic property of the CFTR Cl− channel and not the result of pore block.

Abstract:

A novel internal compensation technique named dual frequency compensation is proposed to improve the stability and the transient response of the on-chip output capacitor three stage low-drop-out linear voltage regulator (LDO). It exploits a combination of amplification and differentiation to sufficiently separate the dominant pole from the first non-dominant pole so that the latter is located after the unity gain frequency regardless of the load current value. The proposed LDO regulator is analyzed, designed, and simulated in standard 0.18 µm low voltage CMOS technology. The presented LDO regulator delivers a stable voltage of 1.2 V for an input supply voltage range of 1.35-1.85 V with a maximum line deviation of 4.68mV/V and can supply up to 150mA of the load current. The maximum transient variation of the output voltage is 54.5 mV when the load current pulses from 150mA to 0mA during a fall time of 1µs. The proposed LDO regulator has a low figure of merit compared with recent LDO regulators.

Abstract:

This paper presents an innovative driver circuit for a new current regulator of the multilevel inverters. The proposed regulator has a PI controller to guarantee the optimum tracking for the reference current. This proposed regulator has the advantage of integration between the PI controller and the multicarrier switching operation. This regulator fits the operation of multilevel and cascaded converters. The suggested current regulator is compared with several existing current regulators of the multilevel and cascaded converters. The performance of the proposed regulator is verified using simulation results in comparison with the performance of the common existing current regulators for the multilevel inverter. Moreover, this paper shows the performance of the new regulator in power system applications.

Abstract:

Linear power supplies are commonly used power supplies for many applications. They have some drawbacks such as low efficiency, difficulty in thermal management and also in regulation of the output voltage. Some of these drawbacks can be overcome by Switch Mode Power Supplies (SMPS). One of the best-suited applications of SMPS is for space applications that require power supplies which are lighter, smaller, more efficient and highly reliable. Multiple-output DC-DC converters are an important topology of SMPS that can be used for space applications. But, in multiple output converters usually, only the master output is regulated and the other outputs are left unregulated and this can result in cross-regulation. In this paper, post regulators such as Magnetic amplifiers (Mag-amp) and Low DropOut regulator (LDO) are proposed to regulate each output and also to improve load regulation. In addition to this, the input voltage feed-forward control technique is proposed to control the duty cycle of the switch, which is dynamically faster and provides better line regulation when compared to the voltage feedback controller. Besides, over current protection circuit for the converter is discussed in detail. Keywords: Cross regulation effect, Mag-amp and LDO, multiple output forward converter, output over current protection, voltage feed forward control.
