Abstract

Abstract: The zero-voltage switching (ZVS) phase-shifted full-bridge (PSFB) converter has the advantages of simple circuit topology, low voltage and current stress, and controllable working frequency. If applied to the dc charging pile, it can effectively reduce the switching loss and improve the overall operating efficiency of the power supply system. The working principle of ZVS PSFB converter is analyzed, and the main circuit topology of the converter is determined by combining with the technical specifications required by the dc charging pile. Based on PI control, wide range dc voltage output of converter is realized. Finally, PSIM is used to carry out simulation test on the PSFB converter, and the simulation results verify the correctness of ZVS operation and the effectiveness of closed-loop control.
