This letter presents a high-efficiency and high-power passive rectifier for wireless power transfer applications. A commutation capacitor is added at the input of the rectifier to improve its performance. The output current is transformed from the discontinuous conduction mode to the continuous conduction mode. The feasibility of the circuit has been verified experimentally on a 3.2-kW prototype and a maximum efficiency of 94.0% has been achieved.
