Research on Space Vectors Over-modulation Strategies of Two Stage Matrix Converter

Peng Kang

Abstract

The dual modes and single mode over-modulation strategies were introduced into the rectifier and inverter of two stage matrix converter based on space vector modulation to improve the voltage transfer ratio.The principle of the two over-modulation strategies for two stage matrix converter was analyzed,the simulation realization of arithmetic was given,and compared the output performance of two over-modulation strategies.The simulation results demonstrate that the voltage transfer ratio can be up to 1 and the quality of output waveforms is good,which provides a theoretical reference for the further research and application.
