3-Ph 3-Level Zvs Dc-Dc Converter

Abstract

This paper proposes development of soft switching scheme for three phase three level DC-DC converter for different duty cycles to achieve ZVS for all switches. The ZVS is achieved with output inductor and leakage inductor of transformer. This paper describes the main operational modes of proposed converter for different duty cycle and simulation results are observed and compare the switching losses of proposed converter with and without ZVS.
