Description
Summary:This paper presents a simple space vector modulation (SVM) strategy for a three-phase indirect matrix converter (IMC) to reduce common-mode voltage (CMV) and output harmonic distortion. To suppress the CMV peak value 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. However, the output waveform quality of the IMC deteriorates due to the absence of zero voltage vectors. To overcome this problem, this paper proposes to redesign control of the rectifier stage by utilizing three active current vectors instead of two, as is common. Consequently, a constant average DC-link voltage is achieved, which can improve the output performance in terms of output voltage and current harmonic distortion. Compared to the existing strategies, the proposed strategy can reduce the CMV and maintain output harmonic distortion without increasing the computation burden. Implementation of the proposed strategy is also straightforward and simple. Simulated and experimental results are provided to verify the effectiveness of the proposed strategy.
