Abstract
A double-sided LCC compensation network and a tuning method are proposed for a wireless power transfer system. With the proposed topology, the resonant frequency is independent of coupling coefficient and load conditions. The parameter values are tuned to realize zero voltage switching (ZVS) for the sending side switches. A wireless charging system with up to 7.7 kW output power was designed and built using the proposed topology and achieved 96% efficiency from DC power source to battery load.
