In this study, a 1.5 [kW] on-board battery charger for neighborhood electric vehicles was developed. The developed charger has a built-in power factor correction circuit and a resonant phase shift full-bridge (PSFB) for power conversion. Although an additional snubber is not used, the switching noise generated in the switch and the diode is reduced, owing to the built-in resonant-type PSFB converter, and the desired improvement in noise reduction and efficiency of input/output is achieved. The power conversion controller was controlled using a dedicated integrated circuit.
