Abstract

This paper proposes an auxiliary power module - integrated EV charger. The proposed integrated charger shares a switch leg of the LLC converter of OBC and the PSFB converter of APM. By sharing the common leg, which is the lagging leg of the PSFB converter, ZVS range of the lagging leg, is extended and RMS current of the common leg is reduced during the simultaneous charging mode due to current cancellation effect. In addition, OBC and APM in the proposed integrated charger can operate simultaneously without additional component. Based on these characteristics, the proposed integrated charger cannot only achieve high power density and low cost, but also increases the efficiency. A prototype of the proposed integrated EV charger consist of the 3.6kW LLC converter and the 1kW PSFB converter is built and tested in order to verify the performance and theoretical claims.
