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...
The efficiency is the important factor for the power converter that is used in photovoltaic application. This paper proposes a new SVPWM method for three - level TNPC topology to improve the efficiency by minimize the number of switching. The proposed method is based on the virtual flux vector. By applying proper non-zero voltage vectors, a quasi circle will be created. The performance of the converter...
