Performance of Dual-Bridge High Frequency Resonant DC/DC Converter for Energy Storage Application

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 LC-L resonant converter is carried out for resistive and battery load. The simplified steady state analysis using complex ac analysis is given and conditions for zero voltage switching are presented accordingly. A closed loop control operation of a converter using PI controller is suggested to minimize the reverse power flow for battery load.
