In this paper, a new improved multilevel inverter topology on the basis of IDFCM topology is proposed. By adding three high frequency switches and one DC voltage sources, this topology is capable to generate number of the output voltage levels which multiplied further than two toward the IDFCM topology.

Abstract

In this paper, a new improved multilevel inverter topology on the basis of IDFCM topology is proposed. By adding three high frequency switches and one DC voltage sources, this topology is capable to generate number of the output voltage levels which multiplied further than two toward the IDFCM topology. In order to control the used switches, a new control strategy based on the phase shifted carrier pulse width modulation method is presented which guarantees the self-adjustment of the voltages on the flying capacitors. The proposed topology by applying the presented control method is simulated through PSCAD/EMTDC software and results are shown to examine the validness of the implemented control method.
