摘要:摘要:无线充电系统(wireless charging system, WCS)可以提升充电装置的便捷性与安全性。针对快速且准确地优化设计叠层线圈式磁耦合机构(solenoid and double D pads, SDDP)参数问题，采用正交试验法及磁场仿真软件，研究了正交试验法优化叠层线圈式磁耦合机构参数的效果，给出了优化过程及磁耦合机构优化后的仿真结果分析。结果表明，采用正交试验法对叠层线圈式磁耦合机构的匝数配比进行优化设计，所需仿真次数由256次减少至16次，节省了时间与人力成本，且优化后机构具有良好的抗偏移性能：沿x方向单轴偏移180mm过程中，互感波动范围为-20%~10%，沿y方向单轴偏移120mm过程中，互感波动范围为-20.4%~18.9%。
Abstract:Abstract:Wireless charging systems improve the ability of convenience and security of the charging mechanism.To accurately and rapidly optimize the parameters of Solenoid and Double D-pads(SDDP), the effect of the orthogonal test method to optimize the parameters of SDDP is studied by adopting the orthogonal test and magnetic simulation software.The optimization progress and the analysis of simulation results of SDDP are given.The results show that the simulation times are deduced from 256 times to 16 times by using the proposed optimization method to optimize the number of SDDP turns.Therefore, the time and labor costs can be saved.Besides, the mutual inductance of optimized SDDP varies from -20% to 10% within 180mm misalignment distance on the x-axis and ranges from -20.4% to 18.9% within 120mm misalignment distance on the y-axis, which indicates that optimized SDDP has an excellent ability of anti-misalignment.
