Abstract

In this paper, an LCC-LCC compensated 50 kW 3phase (3ϕ) wireless charging system with nonzero interphase mutual inductance is demonstrated. The 3ϕ-LCC compensation is designed considering a nonzero mutual-inductance among the phase-coils to meet resonance criteria, balance voltages and currents of the resonant tank components, achieve desired voltage gain, and ensure the zero-voltage switching (ZVS) operation. An experimental prototype of the 3ϕ-LCC-LCC compensation circuit is built for a 50 kW bipolar coil-based 3ϕ wireless charging system. The prototype system was tested at rated 50 kW power for evaluating the efficiency, ZVS operation, electric and magnetic field emissions, and thermal characteristics. The experimental results show 94.3% dc-to-dc efficiency and only 4.4 μTrms magnetic field emission at the rated 50 kW output power.
