Abstract:

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.

Abstract:

Diodes are popularly used in rectifiers, which convert an ac signal into a unidirectional signal. They produce a fixed output voltage only. However, controlled switches such as thyristors are used to vary the output voltage of a converter by adjusting the delay or firing angle α of the thyristors. Phase-controlled converters are simple, efficient and less expensive. There are both single-phase and three-phase converters depending on the input supply. We also have half-wave and full-wave converters. The half-wave converter has only one polarity of output voltage and current, while for the full converter, the polarity of the output voltage can be either positive or negative. The purpose of this paper is to investigate the operation of the Single-phase full-wave rectifier. Load current for the controlled full-wave rectifier with R-L load can be either discontinuous or continuous. The paper shows how the rectifier transits from discontinuous current operation to continuous current operation.

Abstract:

This paper deals with a battery energy storage system (BESS) in only one of its multiple operating modes, that is when the BESS is charging the battery bank and with the focus on the control scheme design for the BESS input stage, which is a three-phase LCL-filter PWM rectifier. The rectifier's main requirements comprise output voltage regulation, power factor control, and low input current harmonic distortion, even in the presence of input voltage variations. Typically, these objectives are modeled by using a dq model with its corresponding two-loop controller architecture, including an outer voltage loop and a current internal loop. This paper outlines an alternative approach to tackle the problem by using not only an input–output map linearization controller, with the aim of a single-loop current control, but also by avoiding the dq modeling. In this case, the voltage is indirectly controlled by computing the current references based on the converter power balance. The mathematical model of the three-phase LCL-filter PWM rectifier is defined based on the delta connection of the filter, which accomplishes the requirements of a 100 kW BESS module. Extensive simulation results are included to confirm the performance of the proposed closed-loop control in practical applications.

Abstract:

Purpose: Two possible variants of power sources are considered: controlled three-phase bridge rectifier circuit with a step-down transformer and a pulse converter, getting power from the mains via uncontrolled three-phase bridge rectifier (Larionov circuit) for bringing into rotation with the required frequency of wheel-motor units of electric locomotives and electric trains at the position of indiscriminate diagnosis of bearings. In both cases, it is assumed that power sources receive electro-energy from a depot circuit — 380/220 V, 50 Hz. The comparison of proposed power supply options based on the assessment of energy consumption efficiency is carried out. A capacity coefficient and capacity loss in power supplies are used as measures for energy-consumption efficiency. Methods: Analytical methods are used to determine capacity losses in a transformer, controlled three–phase thyristor rectifier, uncontrolled three-phase diode rectifier, input filter of a pulse converter, IGBT transistor and reverse diode of a pulse converter. Results: Energetical indicators were determined: power losses in a transformer, a controlled three–phase thyristor rectifier, an uncontrolled three-phase diode rectifier, an input filter of a pulse converter, an IGBT transistor and a reverse diode of a pulse converter. Based on the pursued assessment of the energetical indicators of power supply two options, it is concluded on feasibility of transformer-free circuit application in bearings’ position of vibration-acoustic diagnosis. Practical importance: A variant of an energy–efficient power supply for the position of indiscriminate vibroacoustic diagnosis is proposed, which includes an uncontrolled semiconductor rectifier and a pulse converter, accomplished using an IGBT transistor.

Abstract:

Purpose The model for digitally controlled three-phase pulse width modulation (PWM) boost rectifiers is a sampled data model, which is different from the continuous time domain models presented in previous studies. The controller, which is tuned according to the model in continuous time domain and discretized by approximation methods, may exhibit some unpredictable performances and even result in unstable systems under some extreme situations. Consequently, a small-signal discrete-time model of digitally controlled three-phase PWM boost rectifier is required. The purpose of this paper is to provide a simple but accurate small-signal discrete-time model of digital controlled three-phase PWM boost rectifier, which explains the effect of the sampling period, modulator and time delays on system dynamic and improves the control performance. Design/methodology/approach Based on the Laplace domain analysis and the waveforms of up-down-count modulator, the small signal model of digital pulse width modulation (DPWM) in the Laplace domain is presented. With a combination of state-space average and a discrete-time modeling technique, a simplified large signal discrete time model is developed. With rotation transformation and feed-forward decoupling, the large-signal model is decoupled into a single input single output system with rotation transformation. Then, an integrated small signal model in the Laplace domain is constructed that included the time delay and modulation effect. Implementing the modified z-transform, a small-signal discrete-time model is derived from the integrated small signal model. Findings In a digital control system, besides the circuit parameters, the location of pole of open-loop transfer function is also related to system sampling time, affecting the system stability, and the time delay determines the location of the zero of open-loop transfer function, affecting the system dynamic. In addition to the circuit parameters discussed in previous literature, the right half plane (RHP) zero is also determined by the sampling period and the time delay. Furthermore, the corner frequency of the RHP zero is mainly determined by the sampling period. Originality/value The model developed in this paper, accounting for the effect of the sampling period, modulator and time delays on the system dynamic, give a sufficient insight into the behavior of the digitally controlled three-phase PWM rectifier. It can also explain the effect of sampling period and control delay time on system dynamic, accurately predict the system stability boundary and determine the oscillation frequency of the current loop in critical stable. The experimental results verify that the model is a simple and accurate control-oriented small-signal discrete-time model for the digitally controlled three-phase PWM boost rectifier.

Abstract:

A discontinuous conduction mode (DCM) three-phase single-ended primary-inductor converter (SEPIC) is presented in this article. The analyzed converter operates as a high-power factor stage in AC–DC conversion systems. As its main features, it presents three controlled switches and a single control signal with simple implementation and low-current harmonic distortion. The converter topology, its design equations, and its operation modes are presented as well as a simulation analysis considering a 3 kW–220 V three-phase input to 400 V DC output converter. The experimental results are included, considering as an application the rectifier stage in low-power wind energy conversion systems (WECS) based on a 1 kW permanent magnet synchronous generator (PMSG) with variable voltage frequencies. From the analysis performed in the paper and the simulation and experimental results revealed, it is concluded that the converter is indicated to be employed in any AC–DC low-power conversion system, such as DC distribution systems, and distributed generation or hybrid systems containing variable-frequency generation.

Abstract:

This paper presents a controller design for a threephase controlled rectifier using artificial intelligence techniques to regulate the DC-bus voltage. The averaging model of the power electronic system is used as an objective function instead of the model from software packages. The averaging model is derived from the DQ modeling approach in which the dynamics of the transmission line and power converter are taken into account for the controller design. The results show that the proposed method can efficiently obtain the best performance of the output waveform compared with the classical method. Moreover, this approach is convenient and flexible for electrical engineering to design the controller of power electronic systems with the best output performance.

Abstract:

In order to achieve the low cost and high performance control of three-phase PWM rectifier, a direct power control (DPC) strategy based on a new-style virtual flux-linkage observer is proposed. The model of three-phase PWM rectifier and the principle of virtual flux-linkage vector control are introduced firstly. Then, in order to avoid the effect of integral initial value and cumulative deviation, three first-order low-pass filters are cascaded to replace the pure integral link; an improved virtual flux-linkage observer of three-phase power grid is presented. From the observed virtual flux-linkage, the voltage and instantaneous power of three-phase power grid are online estimated. On this basis, the power grid voltage sensorless direct power control system of three-phase PWM rectifier is designed. Simulation results have shown that, both in the rectifying state and in the inverting state, the power grid side current and the DC side voltage of three-phase PWM rectifier all can be effectively controlled; the high power factor operation of three-phase PWM rectifier is realized.

Abstract:

Abstract This paper presents a novel converter which can reduce the harmonics like the conventional multipulse converters with input three phase transformer. To reduce total harmonic distortion of input current and improve the weight and size of converters, it is suggested to use multi-pulse rectifiers with an electronic phase shift. The basic module is a 6-pulse rectifier on fully controlled switches with the reverse blocking ability. Switching frequency either coincides or is twice the power frequency. The proposed solutions allow refusing from the electromagnetic phase-shifting devices (power transformers or auto-transformers) and thereby significantly reduce the weight of the device. Unlike power factor correction systems with high-frequency modulation, the proposed converters are significantly different, as they have better electromagnetic compatibility and the virtual absence of dynamic switching losses of power switches.

Abstract:

This paper presents the design and analysis of a novel polygon connected autotransformer based 30-phase ac-dc converter which supplies Direct Torque Controlled Induction Motor Drives (DTCIMD’s) in order to have better power quality conditions at the point of common coupling. The proposed converter output voltage is accomplished via three paralleled 10- pulse ac-dc converters each of them consisting of 5-phase diode bridge rectifier. An autotransformer is designed to supply the rectifiers. The proposed converter requires only three inter-phase transformers in the dc link that leads to the reduced kilovolt ampere rating, size, weight, and cost of the proposed rectifier. The design procedure of magnetics is in a way such that makes it suitable for retrofit applications where a six-pulse diode bridge rectifier is being utilized. The aforementioned structure improves power quality criteria at ac mains and makes them consistent with the IEEE-519 standard requirements for varying loads. Furthermore, near unity power factor is obtained for a wide range of DTCIMD operation. A comparison is made between 6-pulse and proposed converters from view point of power quality indices. Results show that input current Total Harmonic Distortion (THD) is less than 3% for the proposed topology at variable loads.

Abstract:

In this study, the feedback effects of a three-phase half-controlled rectifier (also known as a semiconverter) to three-phase AC power grid was analyzed. Special attention was paid to the identification of harmonic order of the phase current. As a reference point for analysis, the mathematical model of an uncontrolled rectifier was used. The harmonic order of the phase current was identified by displaying the measurement results as well as using a mathematical model that is easily applicable, although this is unusual for harmonic analysis because it is based on time domain data. For this purpose, laboratory models of uncontrolled and half-controlled rectifiers were assembled. For both converters, the results obtained by practical laboratory measurements were compared to the mathematically obtained results, with the commutation in the mathematical model being ignored. The effects of commutation were analyzed in more detail for the laboratory model. For the semiconverter, the characteristic waveforms were studied for few different firing angles of the thyristor. Additionally, total power factor and total harmonic distortion of phase current were determined for all chosen firing angles. Finally, a comprehensive conclusion was drawn based on theoretically and practically obtained results on the appearance of even-order current harmonics, which should be taken into consideration when designing input filters and which contributes to power quality of the AC power grid.

Abstract:

The vast majority of electricity is used by industrial facilities in a converted form. At the same time, the use of semiconductor converters to obtain the required load parameters is intensively increasing. Current trends in the development and improvement of semiconductor converters are aimed at energy saving by improving their quality of work and reducing the impact on the power supply, load, and related consumers. Frequency converter with DC insert has become widespread and widely used. Its scheme is mainly based on an uncontrolled diode rectifier and an autonomous voltage inverter. Uncontrolled rectifiers are simple and reliable, but have two main disadvantages: the impossibility to recover electricity to the supply network and distortions of the source current shape. We can get rid of these disadvantages by using an active rectifier made according to the voltage source scheme instead of an uncontrolled rectifier. The operation of an active rectifier significantly depends on the type of its control system structure. This article aims to to improve the structure of the switches control system of the active rectifier scheme – voltage source built using a vector calculation algorithm; creation of a MatLab model of a three-phase active-controlled rectifier operating with a fixed modulation frequency and analysis of the influence of the input inductance value on the quality of its operation. The simulation results confirm that the improved structure of the vector control system proposed by the authors ensures high-quality operation of the active rectifier and electromagnetic compatibility of the frequency converter with the power supply network at the level allowed by the standards; simplification of the representation mathematical apparatus of the generalized vectors of currents and voltages at the construction of a vector control system of the active rectifier – voltage source practically did not influence qualitative indicators of the converter work in any way; a network filter must be used to eliminate the final distortions introduced into the source voltage by an additional nonlinear load.

Abstract:

This paper presents the development of a wind Interior Permanent-Magnet Synchronous Generator (IPMSG) based bipolar DC microgrids along with various switch-mode rectifiers. Firstly, the wind IPMSG is established and adequately controlled to possess satisfactory generating characteristics during different driven speeds and loads. Later, the boost switch-mode rectifier (SMR) based bipolar DC bus is established. Further, three-phase single-switch (3P1SW) boost SMR, three-phase two-switch (3P2SW) three-level boost SMR, and a three-phase three-switch (3P3SW) Vienna SMR are comparatively evaluated. Along with the proposed robust voltage and current controls, a well-regulated microgrid DC-bus voltage is established. Moreover, the voltage balancing control is proposed to minimize the imbalance in the bipolar DC-bus voltage. For the wind IPMSG having Vienna SMR, the commutation angle setting is adjusted to use the reluctance power component effectively.

Abstract:

The article presents various concepts of three-phase power rectifiers with improved quality of converted electric power. This effect is obtained by modulating the currents in the DC output circuits of the rectifiers by means of power electronics controlled voltage or current sources, working as a so-called voltage or current modulators. For further quality improvement of the grid currents of the analyzed systems, it was proposed to use an additional controlled current source connected in parallel to the DC load, hereinafter referred to as a supporting system. The original elaborated method of controlling this source (supporting system) was presented. The main goal of the work was to propose a solution for an effective method of improving the quality of energy conversion in rectifier systems, especially high power ones, by using controlled current sources in DC circuits, operating as the power electronics current modulator and the supporting system.

Abstract:

This article introduces a novel and effective diagram based on direct instantaneous power control (DPC) of a PWM-controlled rectifier connected to the grid without a switching table. An optimum control vector of the PWM rectifier's input voltage, which depends on the switching states determined by a Petri nets controller, is adopted. This approach limits the instantaneous detection errors of reactive and active powers, maintains the DC bus voltage at a reference level, and ensures current close to a sinusoidal wave, guaranteeing operation at a unit power factor. The instantaneous tracking errors of active and reactive powers and the angular position of the voltage are used as input variables for the proposed controller, which then selects the best control vector for the converter based on the transition of a Petri net. The significant advantages of DPC based on Petri nets compared to traditional switching tables are that hysteresis comparators are not required, and the classical regulation of active and reactive powers is achieved in all sectors. Simulation and testing findings demonstrated excellent performance, supporting the viability of the suggested control approach using Petri nets.

Abstract:

Controlled rectification is the process of obtaining a controlled output DC voltage from a constant AC voltage. This can be used in the speed control of the DC motor to provide rapid torque control and a quick starting response. In this work, a three-phase half-controlled bridge rectifier has been used. The average output DC voltage varies smoothly by varying the firing angle (α). Different methods of analysis such as state-space and Fourier-series, are used to obtain the performance of the DC motor fed from the bridge-rectifier supply. However, these methods do not deal with the prediction of the discontinuous conduction phenomenon which occurs during the operation of the DC motor with a variation of delay angle. This paper deals with the prediction of performance characteristics during the operation of the DC motor fed by a 3-phase half-controlled bridge rectifier, including the transient as well as steady-state operation with a variation of delay angle as well as application of load torque at starting.

Abstract:

This paper presents two robust controls techniques: current control in the dq reference frame and direct power control (DPC) applied to a three-phase PWM rectifier to achieve efficient dc voltage regulation, unit power factor control and harmonic distortion rate reduction. Simulations were performed using Matlab/Simulink software. According to these results, the DPC direct power control seems to be more efficient than the current control in the dq reference frame, which has a lower harmonic distortion rate, and the DC voltage follows its new reference for the two developed controls. However, the response time, overshoot and oscillations of the controlled quantities, as well as the exponential convergence of the errors for the transient regime and the setpoint change, are different. It can be seen that the best values of the latter are those obtained by applying the DPC direct power control, which is considered to be the best performing and most efficient control compared to the other control.

Abstract The paper presents a study regarding the implementation of two representative grid synchronization methods, intended to be used in the control structure of a three phase switch mode voltage rectifier. The methods considered are the Synchronous Reference Frame Phase Locked Loop (SRF PLL) and the Double Synchronous Frame Phase Locked Loop (DSRF PLL), respectively. These synchronization methods have been compared on a real time development system type dSpace 1104 from the point of view of their performance in case of an unbalanced mains voltage system. Finally, the influence of the chosen grid synchronization method on the performance of a synchronous reference frame controlled three-phase switch mode voltage rectifier is studied by simulation, and better results are demonstrated to be provided by the use of the DSRF PLL.

Abstract:

The main part of electricity is used by industrial plants in a converted form and the use of semiconductor converters is growing rapidly. The requirements for the quality of semiconductor converters are increased. And their impact on the power supply, load and related consumers is increased too. One of the most popular converters in the segment of low and medium power drives is a frequency converter made on the basis of a three-phase stand-alone voltage inverter. A significant disadvantage of such converters is the use of a diode rectifier at the input of the circuit, which has disadvantages as the inability to recover electricity to the mains in the mode of dynamic braking of an induction motor and significant distortions of the mains current. These disadvantages can be eliminated by using an active rectifier instead of a diode rectifier, which provides a sinusoidal shape of the mains current in phase with the mains voltage and the possibility of bidirectional energy exchange with the load. The efficiency of the active rectifier-voltage source is determined by the selected control algorithm of the circuit switches and the correct task of the inductance of the input choke. A mathematical model of a three-phase active rectifier-voltage source, working with a fixed modulation frequency with a vector algorithm for building a control system and analysis of the influence of the input inductance on the quality of its work was created. From the simulation results it became obvious that the proposed structure of the control system provides stable operation of the converter and acceptable standards for electromagnetic compatibility with the mains at a fixed modulation frequency; the proposed algorithm for calculating the value of the input inductances allows you to correctly select their allowable value, and obtained in the simulation of the dependence allows you to most accurately determine the value of the input inductances on the allowable level of distortion of mains current and supply voltage.

This research article presents the method to control the DC voltage of the boost converter by using a proportional-integral (PI) controller. With AC voltage from a wind turbine generator, converting to DC voltage level by rectifier, this DC voltage controlled by PI controller is to control boost converter that sends DC links to the inverter which converting alternating current voltage to direct current voltage through three-phase load and to the grid-connected system. For switching the IGBTs in the inverter, the PWM signal, on the hysteresis current control, is controlled by the signal from the detected reference voltage based on the grid-connected system and the voltage from a wind turbine generator. The tests made the comparison of results from the simulation with the MATLAB/Simulink program and result from the hardware on the prototype. The power quality results, such as harmonic, power factor, are in acceptable ranges.

Abstract:

Abstract This study investigates the characteristics of significant amplitude-frequency variations and periodic phase sequence changes in the output electrical energy of linear internal combustion power generation systems. It conducts an analysis of the power generation characteristics of linear motors during stable operation and investigates rectification control strategies for three-phase electrical energy. Traditional control strategies involve the combination of three-phase uncontrolled rectification and chopper circuits. However, the three-phase uncontrolled rectifier bridge can lead to severe current discontinuity in the phase current of the linear motor, affecting the stability of the power generation system. This study proposes a Boost-type controllable rectifier based on the active short-circuit of the upper bridge arm of ASC, employing a composite control strategy of PWM-PFM. Simulation results indicate that the output bus voltage under ASC control can be stably controlled, with a higher voltage peak compared to uncontrolled rectification, and without causing a current discontinuity in the motor-side phase current. This approach is capable of adapting to loads of varying voltage levels and offers superior control performance.

Three phase rectifier with variable capacitors is the selected current harmonic source and the distortion at current waveform is controlled by the capacitance values. Initially the operation losses under rated load is measured and then followed with measurement with nonlinear load. At the end of this paper, both type of operation losses is compared and differentiated.
