摘　　要：为解决电动汽车无线充电系统在多角度弯道下互感波动剧烈问题,采用了两个规格相同圆形线圈进行互感补偿,并通过理论推导和仿真验证,得出补偿线圈最优化匝数和统一规格参数。通过搭建COMSOL Multiphysics、Matlab/Simulink结合的仿真平台进行验证。实验表明:在转弯时采用两个圆形线圈进行补偿,互感波动率约为0.5%;同时,在抗横向偏移方面,能量接收系统的电压在左右偏移5 cm范围内能保持稳定。该设计实现了降低电动汽车无线充电系统中弯道互感波动的目标。In order to solve the problem that the mutual inductance fluctuates violently in the wireless charging system of the electric vehicle around the multi-angle bend,two circular coils of the same specification are used for the mutual inductance compensation.Through the theoretical derivation and simulation verification,the optimal turns and the uniform specification parameters of the compensation coil are obtained.Through the establishments of the COMSOL Multiphysics platform and the Matlab/Simulink platform,the simulation platform is verified.The experiment shows that around the bend,two circular coils are used for the compensation,and the mutual inductance fluctuation rate is about 0.5%;at the same time,in the aspect of the anti-lateral deviation,the voltage of the energy receiving system can keep stable within 5 cm of the left-right deviation.This design realizes the goal of reducing the mutual inductance fluctuation in the wireless charging system of the electric vehicle around the bend.
