A Phase-Shifted Full-Bridge Converter Used for DC Charging Pile

IOP Conference Series: Materials Science and Engineering, 2020
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 ...
