N2 - Coil parameters variation due to manufacturing error or environment causes received power and efficiency decrease in wireless power transfer(WPT). Especially, self-inductance variation causes resonance misalignment, and the system can't maintain ideal characteristics including nominal received power. This paper proposes a power compensation method that controls only the receiving (Rx) side when coil parameters change. By using LCC circuit on the transmitter (Tx) side, wireless communication and power fluctuation due to coil parameter change on the Tx side are eliminated. On the Rx side, the received power is controlled by a DC/DC converter while the resonance misalignment is compensated by a branched capacitor. The proposed method can control the power and compensate the resonance misalignment concurrently. MATLAB Simulink simulation and experimental steady-state measurement results show that power compensation with varying capacitors on the Rx side can improve efficiency by compensating for resonance misalignment.
