Indirect space vector modulated three phase ac-ac matrix converter under abnormal input conditions

Matrix converter is a single-stage Converter which directly connects a three- phase voltage source to a three- phase load without dc - elements. Therefore, the ac line side abnormal input can deteriorate its output characteristics. In this paper, the indirect space vector modulation method of the matrix converter is investigated and a feed-forward compensation technique to prevent the input voltage harmonics from propagating onto its output characteristics is proposed. Some simulation and experimental results are also presented in this paper to verify the effectiveness and feasibility of the proposed compensation strategy.
