Performance Evaluation of Dual-Bridge High Frequency Resonant DC/DC Converter

Abstract

A bidirectional dual-bridge high-frequency isolated resonant DC-DC converter is gaining more attention in renewable energy system due to its high power density, small size, reducing stress and removing electromagnetic interference noise. In this paper the simulation of dual bridge LCL resonant converter is carried out for battery load. The simplified steady state analysis using complex ac analysis is given and conditions for zero voltage switching is presented accordingly.
