摘　　要：以两线圈等效电路模型为研究对象,重点考虑谐振线圈中通过的高频电流会受趋肤效应与邻近效应的影响,致使导体的有效截面积减小,增大线圈的高频损耗。为了掌握趋肤效应与邻近效应对系统传输的具体影响,在理论分析的基础上研究了线圈参数对系统传输性能的影响规律,并利用Maxwell电磁场仿真软件对圆形导线横截面模型在不同频率情况下进行仿真分析,得到了趋肤效应与邻近效应各自产生的损耗随绕组厚度和频率的变化趋势,由此提出可用铜管来代替相同外径圆形实心导线,以提高材料的实际利用效率。通过理论与仿真结果对比,验证了铜管替代实心导线提高无线电能传输线圈中导线有效截面利用率的可行性,此方法可减小导线在高频电流条件下产生的电阻损耗。This paper takes the two-coil equivalent circuit model as the research object,and focuses on the influence of skin effect and proximity effect on the high-frequency current passing through the resonant coil,which results in reduction of effective cross-sectional area of the conductor and increase of high frequency loss of the coil.In order to master the specific effects of skin effect and proximity effect,this paper uses Maxwell electromagnetic field simulation software to simulate and analyze circular cross-section model under different frequency conditions,and obtains the respective variation trend of loss caused by skin effect and proximity effect with winding thickness and frequency.It is proposed that copper tubes replace solid wires with the same outer diameter in order to increase the effective rate of material use efficiency.The comparison of theory and simulation results verifies the feasibility of using copper tubes instead of solid wires to increase the utilization of effective cross section of conductor in the wireless power transmission coils,and the resistance loss caused by the wires under high-frequency current conditions is reduced.
