Three-phase AC systems interfaced by current source matrix converter with space vector modulation

The paper deals with three-phase AC systems interfaced by frequency converter without DC storage. As an interface between AC systems the current source matrix converter (CSMC) with space vector modulation (SVM) is used. First the averaged state space models are formulated. Next, the results of the analysis based on two frequency D–Q transformation method are presented. Furthermore simulation and experimental test results of ca 1 kVA laboratory model are presented to confirm of the discussed circuit properties.
