Abstract

© 2016 IEEE. In this paper, a SVPWM for an indirect matrix converter (IMC) with dual output inverter has been proposed to eliminate the common-mode voltage (CMV). The presented converter is a combination of the conventional rectifier stage and a dual inverter stage for feeding open-end winding load. The principles of selecting suitable active vectors and zero vectors and then properly arranging the switching sequence in the dual inverter stage are described to eliminate the CMV and to obtain the zero current commutation. The dual inverter IMC with the new SVPWM method significantly eliminates the CMV without any extra hardware. The simulation results are shown to demonstrate that the new SVM method can generate good performance of the input/output waveforms and to provide CMV elimination.
