Abstract
Battery chargers of Plug-in Hybrid Electric Vehicles require high efficiency operation. An LLC resonant DC/DC converter is an excellent choice to reach the high efficiency with reduced current stress. In this paper, a CoolMOS based 10kW full-bridge LLC resonant DC/DC converter with >;97% efficiency is designed. CoolMOS model is utilized to analyze the system loss. Experimental results validate that this charger could charge the load at ~97% efficiency @10kW with output voltage varying from 250V to 400V. When output voltage is between 400V and 450V, the experimental efficiency remains above 95%.
