Novel Control Method for Matrix Converter to Reduce Switching Loss

Abstract

The high differential voltage in commutation under transitional space vector modulation strategy is the cause which results in large switching loss of matrix converter. This paper presents a novel method which rearranges the switching sequence according to the magnitude of input voltages, based on the analysis and calculation of switching loss. Combined with voltage commutation strategy, the new modulation method is utilized in matrix converter. The simulation and experiment verify the validity and feasibility of the proposed method.
