The conventional hysteresis current control (C-HCC) in VIENNA rectifier is one of the simplest and economic strategies. However, current harmonics content and switching number are high, and the coupling among the three-phase cannot be eliminated. The vector control based on SVPWM has a higher control accuracy. However, SVPWM needs a large amount of computation, and the implementation process is complicated. Therefore, it is significant to research a control strategy which can combine the simplicity and rapidity of C-HCC and good control performance of vector control. In this paper, a space vector switching pattern hysteresis control (SVSP-HC) strategy is proposed. It refers to the concept of voltage vector and does not require a carrier. Compared with other hysteresis-based methods, SVSP-HC can get a better current control performance with a similar or even lower equivalent switching frequency. Moreover, the switching numbers of three-phase bridge legs are basically balanced to each other. Finally, the effectiveness and advantages of SVSP-HC have been verified through simulation and experiments.

“…However, this control scheme, such as [6, 7], implements a loss free resistive behaviour at the rectifier input and hence suffer from the same disadvantages. Compensation of the phase lag in the input current (with respect to the grid voltage) in the resistive emulation‐based control schemes (such as [6, 13]) has been attempted in [14] by explicitly incorporating the voltage drop across the line inductor in the modulating waveform. However, the resulting control scheme is far more complicated compared with [6] and requires the use of a digital signal processor for implementation.…”

The three-level, three-switch Vienna rectifier is fast emerging as the preferred topology for the high-power factor front end converter in many applications. Conventional control algorithms for the Vienna rectifier requires sensing of both the supply voltage and the line current. However, in many applications, where an electrical generator feeds the rectifier, the 'supply voltage' is not available for measurement. Even for grid-connected applications the supply voltage may contain significant harmonic distortion which, in turn, increases the harmonic distortion of the rectifier input current. To mitigate these disadvantages, this study presents a novel voltage sensorless control algorithm for the Vienna rectifier. Voltage sensorless control algorithms reported in the literature for this rectifier, so far permit only unity rectifier terminal power factor operation. In contrast, the proposed control algorithm can operate the rectifier at programmable power factor. For the verification of the algorithm, experiments were conducted on a laboratory prototype of the Vienna rectifier using both voltage sensorless and sensor-based control algorithms. Performances of both these algorithms were found to be similar under transient conditions. The voltage sensorless controller achieved better input line current total harmonic distortion in steady state.

“…Better utilisation of DC bus voltage, improved efficiency and low output voltage ripple was demonstrated using the above modified technique, maintaining the advantages of one cycle control (OCC) technique such as no phase locked loop (PLL) and constant switching frequency. The modified OCC for low switching to line frequency ratio was proposed [22], which took into account the voltage drop across the input inductors. An SVM was presented and analysed in [23].…”

Input harmonic and power factor (PF) regulations necessitate the use of front end active PF correction (APFC) circuit for power electronic converters. In recent times, the VIENNA rectifier has become a popular choice for three-phase APFC applications. The converter is a fifth-order system and results in a highly complex model. This calls for a complex control design procedure and involves enormous computation requiring the use of a high end digital signal processor (DSP). This can be simplified if the order of system is reduced. In this study, it is proposed to decouple and analyse the converter as three independent single phase units operating in parallel with current mode control, thereby reducing the order to two, simplifying the analysis and control design. The transfer function of the proposed small-signal model is derived and its Bode plot is drawn. A high bandwidth inner average current controller and a low bandwidth outer voltage controller are designed to obtain a 60°phase margin. With the proposed design, a 10 kW prototype VIENNA rectifier is developed with a low cost analogue integrated circuit (IC) and validated. The results obtained prove the accuracy of the proposed model and effectiveness of the control. Single phase operation is also made feasible with the proposed technique.
