Abstract

AC-AC power conversion particularly for speed control of AC drives is done with single phase cyclo-converters. In this work the single-phase matrix converter (SPMC) topology is used as a cyclo-converter. IGBT are used as power switches. The sinusoidal pulse width modulation has been used for generation of pulses. This paper presents three different switching strategies for SPMC. A comparison is made between these three strategies based on parameters such as type of load to which the strategy is restricted, number of switches kept ON during single time interval, output voltage waveform of SPMC and its THD.
