A Control Technique for Current Source Matrix Converter

This paper investigates a control technique applicable for Current-Source Matrix Converter. Proposed switching strategy realizes algorithm of “relay” regulation of supplying current. Since both input/output currents are regulated the converter provides high power factor and sinusoidal output voltage with controllable magnitude and frequency. In the paper, a general description of proposed control pattern is given. The investigation considers both Indirect and conventional Direct Matrix Converter structures. The simulation is performed and data obtained are introduced with plotted graphs and signal waveforms approving functionality of the circuits. The results are discussed and summarized in last sections.
