摘　　要：提出一种针对车载圆形电磁耦合结构的优化设计方法,该方法以某一假想的圆形电磁耦合结构(直径440 mm)为基本仿真模型,以装置功率传输能力、线圈和磁芯利用率为参照标准,通过三维有限元分析来确定线圈中心位置、匝数和磁芯长度、宽度(匝数)、厚度及数量关键性参数。搭建一个直径600mm输出功率5 kW的圆形电磁耦合结构,通过对比其仿真和实测的纵向及横向偏移特性验证所提优化设计方法的正确性和有效性。A method is presented to design and optimize the circular magnetic coupled structures：a 440 mm diameter basic model is investigated to determine the key factors such as the diameter, number of the coil and the length, width, thickness, number, the position of the ferrites through the 3D finited element analysis based on the standards of power transmission capacity and coil/ferrites utilization.A final 5 kW/600 mm diameter circular magnetic coupled structure is constructed to verify the correctness and effectiveness of the proposed method by its vertical and horizontal offset performance of the simulation and experiment test.
