N2 - Integrating the functionality of battery charging into the propulsion and accessory power system in a plug-in electric vehicle (PEV) can significantly reduce the component count, and thus the cost, weight, and volume for the onboard charger (OBC). Replacing silicon (Si) based power devices with wide-band-gap (WBG) devices can further increase the power density and efficiency and lower the cost as WBG device technology matures and production volume increases. In this paper an isolated, bidirectional integrated OBC and accessory power converter is presented for PEVs employing a boost converter in the traction drive systems and is based on an active front converter (AFC) and a phase shifted dual-active H-bridge converter (PHDAHBC). The AFC utilizes the traction drive inverter, motor, and boost converter and the PHDAHBC is comprised of the transformer and high voltage converter of the 14 V accessory DC-DC converter and an additional H-bridge converter. Experimental results are included for a 6.9 kW OBC integrated into a 60 kW traction inverter with a boost converter using silicon carbide (SiC) MOSFETs and Schottky Barrier Diodes (SBDs).
