Abstract :
A bidirectional on-board charger (BODC) using a full-bridge bidirectional dc-ac inverter and a bidirectional CLLLC dc-dc converter has been designed and built for electric vehicle (EV) on-board charger applications. The dc-ac inverter can be operated in ac-dc with power factor correction (PFC) function. The CLLC dc-dc converter is modified from LLC converter with two separate resonant capacitors on both side of the transformer. A 3.3 kW bidirectional on-board charger prototype has been designed and built. Experimental results show al different operating modes including (1) battery charging mode, (2) vehicle to grid (V2G) mode, and (3) vehicle to house (V2H) mode.
