摘　　要：基于电磁场的基本理论,结合有限元软件,研究了高频效应对无线电能传输系统性能的影响,理论分析和仿真结果表明在高频环境下,集肤效应、邻近效应、涡流等因素都会使系统损耗增加,从而降低系统的传输效率,影响系统工作性能。最后分别采用铜管和利兹线绕制线圈进行无线电能传输的实验,与铜管线圈相比,在相同的工作频率和传输距离下,采用利兹线绕制的线圈能显著提高系统的传输效率,有效减小高频效应对系统的影响。According to the basic theory of electromagnetic field and with the help of finite element software,this paper has investigated and analyzed the issue on the impact of high-frequency effect on wireless power transmission（WPT）system.The theoretical analysis and simulation results show that at high frequencies,skin effect,proximity effect and eddy current would increase the system loss and reduce the transmission efficiency of the system.Finally,by adopting the copper pipe and Litz wire to wind coils,compared experiments are carried out.With the same working frequency and transmission distance,Litz wire can be effectively used to improve the transmission efficiency and reduce the influence of high frequency effect on WPT system.
