A simple and reliable contact-less battery charger for electric vehicles is proposed. It's feature is one body of a power factor correction(PFC) converter and a high frequency inverter(HFI) where the low side switch of an HFI works also as the boost switch of an PFC in discontinuous conduction mode which results in high input power factor and low harmonic distortion without any feed-forward control. The exiting current of the inductive connector, complied with SAEJ1773, effectively works to make the converter operating in ZVS condition. Another feature is that the charger is controlled by only one magnetically coupled variable frequency oscillator which was developed by the authors. This paper analyzes the circuits, gives a design example, shows the inductive connector and the oscillator, and experimental results. An 1.7kW output prototype charger achieved charging efficiency of 87.4% among total one cycle charging, over all efficiency of 90% at heavy load and over 98% of input power factor.
