摘要以单个自谐振线圈等效模型的端口阻抗及耦合线圈之间二端口网络的等效模型为出发点,利用高频有限元仿真软件,结合无线电能传输技术自身的特点,提出分布参数谐振线圈仿真分析以及关键参数的提取方法,通过实验对比验证仿真方法的合理性。另外根据耦合线圈频域阻抗分裂的特点提出耦合系数的计算方法,为进一步分析分布式参数线圈对无线电能传输性能影响的研究提供参考。

Abstract：Abstract Utilizing high frequency finite element simulation software and combining with the characteristics of wireless power transfer (WPT) technique,the key parameters extraction and the simulation method are proposed in this paper,based on port impedance analysis for the single self-resonance coil and two-port network equivalent model for coupled coils respectively.The practical coil is measured as a reference to verify the simulation result.Moreover,the impedance split characteristic has been studied in order to propose the calculation method for the coupling factor.Such work can provide the ideas of the coil design used in WPT system.

Key words： Wireless power transfer magnetic coupling resonance high frequency finite element method parameter extraction
