The Over Modulation Strategy Research and Realization of Two-Stage Matrix Converter

Haixia Chen

Abstract

This paper put forward an over modulation strategy on the analysis of two-stage matrix converter control theory.The strategy is divided into two steps.First,the strategy gets the maximum DC voltage through the control of the rectifier,second,the converter is over modulated,which effectively improve the voltage transfer ratio.A set of experiment device of two-stage matrix converter is built with DSP and CPLD on the basis of over modulation control theory.Experiment result testify that the over modulation strategy can effectively improve voltage transfer ratio,which verify the validity of the strategy.
