Implementation of the Matrix Converter with direct space vector modulation and four-step commutation strategy

This paper deals with matrix converter with implemented vector modulation and four-step commutation strategy. Project of the matrix converter build of 9 bidirectional switches (18 IGBT transistors connected in common emitter configuration) is presented. Also control circuit with two DSP processors and FPGA is discussed. Converter in contest make possible of the output voltage amplitude and frequency change also input power factor can be controlled. Furthermore simulation and experimental tests results of the ca. 1 kVA laboratory model are shown.
