“…The synchronous reference frame controllers usually use the space vector modulators (SVM) to calculate the time divisions of the selected voltage space vectors. Using different duty-ratios and switching sequence for each phase, the control schemes can be configured to take different performance properties into prior consideration [15][16][17][18][19], such as neutral point voltage balancing, switching loss minimization, algorithm simplification, and etc. In addition, the zero-sequence reference injection can also be utilized in this controller.…”

“…In [6] and [7], Vienna rectifiers with added active filter functionality in three-phase three-wire and three-phase four-wire systems have been reported, respectively, but integrating reactive power compensation function into Vienna rectifiers is not mentioned in either study. In [8], integrating harmonic current compensation (HCC) and reactive power compensation (RPC) functionality into the Vienna rectifiers is investigated, and a conclusion is given based on theoretical analysis, which states that because of the unidirectional power flow characteristic, Vienna rectifiers have only limited RPC capability.…”

In this paper, aiming at incorporating reactive power compensation functionality into the Vienna rectifiers, a modified one-cycle-control (MOCC) strategy is proposed by which the three-phase Vienna rectifier can be regulated in leading, lagging or unity power factors with near-sinusoidal input current waveform. First, a brief review of the working principle of the conventional OCC (COCC) strategy is conducted. Then, the MOCC strategy with the functionality of input current phase-shift control is discussed in detail. To mitigate input current distortion caused by the current phase-shift, a method whereby the signal of one phase current which is flowing in an uncontrollable region is injected into the other two phases' current command signals is further presented. The constraints to the implementation of the MOCC scheme and the reactive power compensation capacity of the rectifier under MOCC control are analyzed as well. The proposed MOCC strategy is as easy to implement as the COCC strategy. Moreover, the MOCC strategy also preserves all other advantages of the COCC strategy, such as no phase-locked loop, no frame transformation and constant switching frequency. Finally, the theoretical analysis of the proposed MOCC strategy is fully verified by simulation and experimental results from a 1 kV·A three-phase Vienna rectifier prototype.

“…Compared with the bidirectional rectifier, the unidirectional rectifier adopts fewer fully controlled power switches, which greatly increases the power density of the system and reduces the implementation costs [14]. Taking these considerations into account, many literatures have proposed and demonstrated the potential of unidirectional rectifier that provides RPC or HCC functionalities to mitigate reactive and harmonic currents produced by non-linear loads and uncontrolled passive loads [15][16][17][18][19][20][21].…”

In order to improve the power quality, many researchers in the worldwide are committed to investigating the feasibility of integrating reactive power compensation (RPC) and harmonic current compensation (HCC) functionalities for unidirectional rectifier, while the capability of RPC for unidirectional rectifier is very limited. Hence, with the aim of enlarging the capability of RPC for unidirectional rectifier, this article introduces a versatile control strategy for three-phase star-connected unidirectional rectifier. The operating principle and the reasons that limit the capability of RPC for unidirectional rectifier are analysed in detail. On this basis, a novel criterion for judging input current distortion zone is proposed. Furthermore, the additional focus of this article is to quantify the constraint relationship between the degree of input current distortion compensation and input power factor regulating range. Simulations and experimental results are conducted to verify the feasibility and effectiveness of the proposed control strategy, as well as the correctness of the theoretical analysis on the proposed constraints of the input power factor regulation.
