Input Power Factor Control of Three-Phase to Three-Phase Matrix Converters

Abstract

This paper presents input power factor control of three-phase to three-phase matrix converters. The authors propose the three kinds of switching patterns for the matrix converters that can realize arbitrary input-power-factor angle between 0 to 2π and reduce the number of commutations in all of the three phases to four times during the control period. Also, the control range of the output voltage reference in the proposed control scheme is derived. The improvement of the input power factor by using of the proposed control algorithm has been verified by experiments.
