In order to solve the detuning phenomenon caused by the influence of load variation, coupling state and other factors in the wireless power transfer system, the phase-controlled capacitor circuit and corresponding tuning strategy are proposed. The simulation and experimental results show that the resonant wireless power transfer system using the phase-controlled capacitor circuit and the tuning strategy can effectively solve the detuning problem and improve the output power and transfer efficiency.
