Input Power Factor Regulation and Experimental Characteristics of Matrix Converter Control for Reducing Output Voltage Harmonics

Abstract

This paper presents a control scheme of matrix converters for reducing the output voltage harmonics. The feature of the proposed control scheme is the reduction of both the output voltage harmonics and the number of the commutations. The control ranges of the output voltage and input power factor are denoted. Using the input power-factor control, the authors propose the input power factor regulation scheme that compensates for the capacitive current through an input LC filter. The effectiveness of the proposed control algorithm of the matrix converters has been verified by experiments.
