Design and implementation of two-phase matrix converter

Abstract

In this work, a matrix converter has been designed fed by single-phase for speed control of single/two-phase ac motors. This converter can achieve converting directly from single-phase to two-phase. In addition, a new switching algorithm has been proposed to perform ac-ac converting. The proposed Matrix converter can be directly connected between grid and load without using rectifier and dc-link capacitors. Designed converter has been tested for two-phase RL load. The simulation and experimental results of the converter's output voltage and load current are analyzed with the harmonic contents.
