A NOVEL SWITCHING STRATEGY FOR REALIZATION OF SINGLE PHASE MATRIX CONVERTER AS A UNIVERSAL POWER ELECTRONIC CONVERTER

Abstract

This paper presents the realization 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 strategy logic. Induction motor load is connected and the harmonics are verified for Direct Matrix converter. The single structure matrix converter eliminates the rectifier and dc link due to direct AC-AC conversion. Normal sinusoidal PWM and square wave signal generation have been used here, which describes a simple algorithm for multiple purposes. Simulation is performed using MATLAB/Simulink and the results obtained here demonstrate a high performance, low THD matrix converter
