Abstract

Fast charging of electric vehicles is a very desirable feature, especially for long distance travel. For an electric vehicle with a battery capacity of 30 kWh, a fifteen minute charge requires 120 kW charging power. Inductive charging offers a safe and convenient means to accomplish this task. This paper investigates the design criteria of the high power converter for a 120 kW inductive battery charger. Since IGBTs are the devices of choice at this power level, the impact of IGBT losses on the converter design and topology selection is investigated. A comparison between a zero voltage switching and a zero current switching series resonant converter is presented and a final topology selection is made. An experimental 120 kW/75 kHz unit was built and tested in the laboratory to verify the results
