Abstract

This paper proposes a new phase-shift full-bridge (PSFB) DC/DC converter with a reconfigurable secondary side for the wide output voltage range Electric Vehicle (EV) charging application. This converter features a two-secondary-windings transformer and two auxiliary switches. Its rectifying stage can be configured into a full-bridge rectifier when the output voltage is high or as a center-tapped rectifier when the output voltage is low. As a result, the efficiency of the proposed converter at low output voltage can be significantly improved compared to the conventional PSFB converter, making it suitable for the wide output voltage range EV charging application. This paper presents the steady state analytical modeling of the proposed converter, which is verified by circuit simulations. The loss comparison between the proposed converter and the conventional PSFB converter designed for the EV charging application is presented, and the efficiency improvement is for the proposed converter.
