The Global ETD Search service is a free service for researchers
to find electronic theses and dissertations. This service is
provided by the
Networked Digital Library of Theses and Dissertations.
Our metadata is collected from universities around the world. If you manage a university/consortium/country archive and want to be added, details can be found on the NDLTD website.

Optimal control of matrix converters under distorted and unbalanced supply conditions.Richards, Coneth Graham January 2013 (has links)
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.
