Abstract
A 3.39 MHz, 2 kW nominal power DC/DC inductive power transfer systems has been developed and tested experimentally. It achieves 95% peak efficiency at 3 kW output, with a novel parallel push-pull Class E inverter using 650 V, 60 A GaN devices and a full bridge Class DE rectifier with 1.2 kV, 20 A SiC Schottky diodes. The entire system design procedure of the magnetic link and the converters is provided in detail. Such high frequency wireless power transfer systems are targeted towards high power applications with low coupling, where requirements for lightweight and compact receiver sides are crucial.
