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.
