摘要：

Because of different influencing factors in practical operation, such as the stray inductance and capacitance of high-frequency circuit and the environmental variation, the transmission coil parameters of magnetically-resonant wireless power transfer system often drift, impacting the transmission efficiency and power. The relationship between the peak current at transmitting terminal and the symmetry of system is obtained by the simulative analysis based on system model and an optimal matching method with corresponding circuit is designed to track and adaptively tune the peak current at transmitting terminal for the optimal matching of system performance. Experiment verifies the effectiveness of the proposed method. Compared with the mismatched conditions, the proposed method can significantly improve the transmission efficiency and decrease the system sensitivity to stray inductance, capacitance and environmental variation. © 2015, Electric Power Automation Equipment Press.
