摘　　要：以无接触传能系统中的平面螺旋线圈为研究对象,对其分布参数和工作频率的计算方法进行研究。从电磁场理论出发,提出线圈分布参数的计算模型和方法,并建立整个线圈的等效电路模型。在此基础上,分析计算线圈的阻抗特性和变化规律,并确定线圈工作的谐振频率。谐振线圈实测结果表明所提方法合理有效。The numerical model and method for the distributed parameters and resonant frequency of a plane spiral coil are proposed.Based on the general electromagnetic field theory,the model and method of the distributed parame- ters are developed, and the equivalent circuit model of the whole coil is abstracted.From the mentioned work,the im- pedance characteristics of a prototype resonant coil are analyzed and the resonant frequency is ensured.The results show that the proposed method is valid.
