Abstract

This paper presents the hybrid control of a fullbridge LLC series resonant converter as the application of an electric vehicle charging system. the hybrid control combines three control methods to achieve wide a output voltage range of about $75\sim 475 V$, three control methods including the pulse-frequency control method, phase-shift control method, and burst mode. finally, a wide-range output voltage LLC resonant converter prototype is realized. The specification of the prototype is a DC input voltage of SOO V, an output voltage of 75-475V, and maximum output power of 7.5 kW. The peak efficiency is 97.2 %.
