This paper focuses on the design challenges in the design of an efficient, wireless, Level-2 PHEV battery charger. Specifically, this work focuses on the challenges posed by the coupling factor, AC resistance and Q-factor, equivalent load impedance, and need for power electronics. It uses the WiTricity™ system proposed by researchers as a sample system for wireless automotive charging. In-depth study study shows that the output could be modeled as a current source. This paper presents a novel AC/DC rectification and regulation scheme based on a modified boost converter and hysteresis controller. Detailed simulation has been carried out for the system, which shows that the system has 80% efficiency at full load.
