Optimal control of matrix converters under distorted and unbalanced supply conditions.

D. Tech. Electrical Engineering. / A matrix converter is a forced commutated converter which uses an array of controlled bi-directional switches as the main power processing elements to create a variable voltage system with unrestricted frequency. It does not contain any DC link circuit and does not require any large energy storage elements. The output frequency is theoretically infinitely variable as opposed to cyclo-converters. This study will evaluate present modulation techniques for matrix converters. Chapter 2 will review the present direct and indirect modulation techniques for Matrix Converters. Chapter 3 develops the indirect modulation model, based on space vector modulation techniques. In chapter 4 various state space models are developed and an optimised switching pattern, based on the least square error, is developed.
