摘要
为提高大功率无线电能传输(WPT)耦合机构的耦合能力和抗偏移特性,以大功率电动汽车静态无线充电为例对耦合机构进行优化研究。使用COMSOL Multiphysics有限元仿真软件对双D形线圈进行磁场耦合建模,对耦合机构的耦合能力进行分析,得出最优的线圈匝数和线径。采用LCC-S混合拓扑谐振补偿电路,进行“磁场+电路”场路耦合建模研究,充分了解WPT系统的磁场特性和电路特性,分析双D形线圈的抗偏移特性。相比同尺寸的矩形线圈,双D形线圈在Y方向具有更好的抗偏移特性。
In order to improve the coupling ability and anti-offset characteristics of the high-power wireless power transfer(WPT)coupling mechanism,this paper proposes to take the static wireless charging of high-power electric vehicle as an example to optimize the coupling mechanism.The finite element simulation software COMSOL Multiphysics is used to model the magnetic field coupling of double D-shaped coil,and the coupling ability of the coupling mechanism is studied.And the optimal choice of coil turns and wire diameter are obtained.The modeling research on the“magnetic field+circuit field”coupling is conducted by using the resonant compensation circuit of the LCC-S hybrid topology,fully understanding the magnetic field characteristics and circuit characteristics of the WPT system,and analyzing the anti-offset characteristics of double D-shaped coil.Compared to rectangular coil of the same size,double D-shaped coil has better anti-offset characteristics in the Y direction.
