摘  要:阐述采用有限元仿真软件COMSOL对线圈进行损耗分析,考虑高频电阻带来的损耗。探讨一个工作于3.4MHz的四线圈结构的设计、仿真和制作。在传输距离为26cm时,仿真得到了四线圈结构的传输效率73%,相应的高频电阻(源线圈和负载线圈为0.05Ω,发射和接收线圈为4.2Ω)。实验结果和仿真结果基本一致,实验测试效率为71%。This paper expounds using the finite element simulation software COMSOL to analyze the losses of the coil,taking into account the losses caused by high-frequency resistors.It explores the design,simulation,and fabrication of a four coil structure operating at 3.4MHz.At a transmission distance of 26cm,the simulation obtained a transmission efficiency of 73%for the four coil structure,with corresponding high-frequency resistors(0.05Ωfor the source coil and load coil,4.2Ωfor the transmitting and receiving coils).The experimental results are basically consistent with the simulation results,and the experimental testing efficiency is 71%.
