A 5kW Zero Voltage Switch Space Vector Modulation (ZVS-SVM) Controlled Three-Phase Boost Converter

This paper proposes a 5kW zero voltage switch space vector modulation (ZVS-SVM) controlled three-phase boost converter. A power circuit of this converter is modified from the conventional three phase boost rectify by combine the active clamp branch. A branch composed of an active switch, a resonant inductor and a clamping capacitor. By used the control techniques to active clamp, the ZVS are occurring at the power switching components. The simulation results can confirm the superiority of this topology to increase the system efficiency up 98 percent. The system has fast response, low total harmonic distortion and steady state error with unity power factor. Moreover, both the main and the auxiliary switches have the same and fixed switching frequency.

This paper presents a space vector modulation strategy for a three-phase indirect matrix converter to reduce the common-mode voltage and maintain the output performance. To reduce the peak value of the common-mode voltage to 57.7% of the input phase voltage, three active voltage vectors are used to generate the desired output voltage with arbitrary amplitude and frequency, instead of using both active and zero voltage vectors as in the traditional space vector modulation strategy. Although the common-mode voltage is reduced, the output waveform quality of the three-phase indirect matrix converter deteriorates due to the absence of the zero voltage vectors. To overcome this problem, the proposed space vector modulation strategy is redesigned to control the rectifier stage of the indirect matrix converter by utilizing three active current vectors instead of two as usual. Consequently, the constant average dc-link voltage is achieved, which can improve the output performance in terms of the output voltage and current harmonic distortion. The simulation is implemented by PSIM software and experimental results are provided to verify the effectiveness of the proposed space vector modulation strategy.
