With the development of the new energy industry in recent years,batteries and battery energy storage technolo-gy have also developed rapidly.Bidirectional DC-DC converter as a circuit that can change the DC energy from one power source to another power source or electrical energy required by the load.It has important significance in improving efficien-cy and can be used for energy transfer between DC bus and battery.The two full bridge structures and the resonant tank in the center form the CLLLC circuit topology.The voltage gain characteristics of the resonant converter are analyzed accord-ing to fundamental wave analysis and experimental waveforms are verified using variable frequency phase shift hybrid con-trol on MATLAB simulation for rated power of 1 kW,DC bus voltage of 400 V and battery voltage of 53 V.
