A simple new control method for matrix converter especially with high number of input phases

Abstract

The matrix converter is a forced commutated cycloconverter (FCC), which get a significant attention in the last several years due to the advance in digital and logic devices technology. The main advantage of FCC compared to the naturally commutated cycloconverter (NCC) is that it has only a single stage conversion. While NCC has restricted frequency conversion ability, the matrix converter can possess a wide range of frequency conversion, depending on the switching strategy. Previous known control methods for matrix converters are such as Venturini method, Roy method, PWM method, predictive control, fuzzy logic control and artificial neural network control. This paper will discuss a simple new perspective of the switching strategy for a new control method of a multi-phase to single-phase or 3-phase matrix converter with the ability to change the input frequency into a lower frequency output and also higher frequency output. The new switching strategy then validated using 36-phase to 3-phase matrix converter modeling and simulation in Matlab/Simulink.
