INVESTIGATIONS ON MATRIX CONVERTER SYSTEMS

INTRODUCTION 1.1 GENERAL Matrix Converters (MC) are essentially 4-quadrant forced commutated converter and are formed by connecting a bi-directional switch cells in a matrix form. They are capable of fabricating an arbitrary output the voltage of variable frequency and magnitude. Factors like single stage transformation of voltage and frequency, bi-directional power flow capability, sinusoidal input and output voltage, more compact size, low weight, and DC link-free architecture, make this converter more attractive than a standard two stage converter.
