Development of a 50 kW Wireless Power Transfer System

A high-power modular wireless power transfer system has been developed intended for use in larger vehicles. This paper presents the design methodology and evolution of the system, including test results. The system utilises SiC switching devices and an 85 kHz operating frequency. 50 kW of wireless power transfer has been achieved over a 200 mm gap at 89% efficiency, showing good promise for the system.
