This paper presents a circuit structure for lead–acid battery. The AC-DC stage employs VIENNA rectifier not only to achieve AC/DC conversion but also realizes low input current THD. To convert DC voltage to 44–64 V, meanwhile to improve the output current capability and efficiency of the converter, an improved phase-shift full-bridge (PS-FB) ZVS PWM double current synchronous rectifier converter is adopted. The VIENNA rectifier utilizes the triple harmonic injection double ramp comparison SPWM (DRC-SPWM) control method to decrease input current THD. The improved DC-DC converter adopts peak current control mode to improve the dynamic response speed of the system. Performance of the proposed circuit is verified by experimental results.
