摘　　要：系统的频率直接影响磁耦合谐振无线电能传输电能质量和传输效率。从新的角度对其进行研究,通过计算由高频逆变电路产生的各次谐波分别对传输系统原副边电流的响应,来分析频率对磁耦合谐振无线传输系统电能质量和传输效率的影响。最后,设计了硬件电路并进行了相关研究,实验结果与理论和仿真分析取得了较好的一致性,证明了该方法的有效性和准确性。结果表明系统的频率越接近谐振频率,原副边电流畸变率越小并且传输效率比较高。The frequency of the system can directly influence power quality and transmission efficiency on the magnetic coupling resonant wireless power transfer. The paper aims to present new aspects on transmission system, by calculating the harmonics generated by the high frequency inverter circuit respectively on the transmission system of the primary and the secondary current response to analyze the frequency on the efficiency and power quality for MCR-WPT. Finally, the hardware circuit is designed and the related research is carried out. The experimental results are in good agreement with the theoretical and simulation analysis, which proves the validity and accuracy of the proposed method. The results show that the system frequency is close to the resonant frequency the primary and the secondary current distortion rate is smaller and the transmission efficiency is relatively high.
