摘要
针对线圈设计过程中各参数之间的特性和相互制约关系,提出了一种在有限尺寸空间下的PCB线圈优化设计方法,综合考虑线圈的匝数、线间距、线宽以及铜厚的影响,以传输效率为优化目标,运用理论与仿真分析相结合的手段,解决了在有限尺寸下的PCB线圈优化设计问题。最后根据优化结果,制作了一组线圈,并对线圈之间的互感及交流电阻进行了测试,测试结果与理论计算和仿真结果基本一致,验证了该方法的可行性。
In the coil design process the characteristics and constraint relationship of variable parameters were considered, and then an optimal design method of PCB coils with the limited coil sizes was proposed, with the transmission efficiency as the optimization objective, this method considers the numbers of turns, the wire spacing, the line spacing and the copper thickness. The problem of optimal design of PCB coils with limited coil size was solved by means of theoretical and simulation analysis. Finally, according to the optimization results, a set of the coils was made. Then mutual inductance between the transmitting and receiving coils and the AC resistance were tested. The test results are basically the same as one of the theoretical calculation and simulation ,which verifies the feasibility of the method.
