A Double L-shaped Anti-offset Wireless Power Transmission Coil and Resonant Network Circuit

针对现有无线传能线圈普遍存在的金属环境适应性差、抗偏移能力较弱的问题,提出了一种双L型抗偏移无线传能线圈及谐振网络电路。基于有限元理论,利用COMSOL电磁场仿真软件,建立了普通8字矩形线圈和双L型抗偏移无线传能线圈的有限元仿真模型,并通过仿真结果验证了该线圈及电路不仅提高了无线传能机构的金属环境适应性,还在各个方向上具有良好的抗偏移性。

A double L-shaped anti-offset wireless power transmission coil and the corresponding resonant network circuit are proposed to address the common problems of poor adaptability to metal environments and weak anti offset ability with respect to currently prevailing wireless transmission coils.Based on finite element theory and using COMSOL electromagnetic field simulation software,finite element simulation models of ordinary 8-shaped rectangular coils and double L-shaped anti offset wireless energy transmission coils are established.The simulation results verified that the coil and circuit not only improve the metal environment adaptability of the wireless energy transmission mechanism,but also have good anti-offset performance in all directions.
