A novel switching strategy for single phase universal matrix converter with hardware implementation [articol]

Abstract

This paper presents the execution of a single phase matrix converter as a universal power electronic converter. The Matrix converter can act as rectifier, controlled rectifier (converter), inverter, chopper, cyclo converter and cyclo inverter by a novel switching logic. Normal sinusoidal PWM and square wave signal generation have been used here, which describes a simple algorithm for multiple purposes. Induction motor load is connected to Direct Matrix converter and its harmonics are verified. Simulation and hardware model is developed and the results obtained here demonstrate a high performance, low THD universal matrix converter.
