摘　　要：针对磁耦合谐振无线能量传输(WPT)系统中谐振线圈的电感、电容选择问题,利用四线圈等效电路模型,根据互感耦合理论对WPT系统的传输特性进行分析,得到了负载接收功率的具体表达式,并进一步分析简化,指出了接收功率与谐振线圈电感电容比的对应关系。然后通过传输距离和耦合系数的分析,对最佳功率传输距离与电感电容比的关系进行了阐述。最后,利用相关实验对上述理论进行了验证。所得结论可为给定距离下电感、电容的选择和优化提供相关理论支持和设计参考。For the problem of selecting inductance and capacitor in resonant coil of magnetic resonant coupling wirelss power transmission（wtrr）, based on the mutual coupling theory,transmission characteristics are analyzed for equivalent four coil model of this resonant system, expression of the load-receive power is obtained.Relationship between the received power and the ratio of inductance and capacitor is also pointed out.By analysising transmission distance and coupling coefficient, the relationship between the optimum power transmission distance and the ratio of inductance and capacitor is described.Finally,the theory is verified by the experimental results.The conclusion can provide the theoretical support and reference for the selection and optimization of the inductance and capacitor at a given distance.
