Five-Level Full-Bridge Zero Voltage and Zero Current Switching DC-DC Converter Topology

This project proposes a development of soft switching scheme for Five level DC-DC converter is used to provide zero voltage switching condition for all the controlled switches. In this paper, the gate pulses are generating from PWM controller. This paper describes the main operational modes of the proposed converter as well as simulation results and also observes and compares the switching losses of the proposed converter with and without zero voltage switching scheme.
