摘　　要：基于高铁列车动态负载的动态耦合基础问题,提出一种发射端为单矩形线圈,接收端为多方形线圈级联的非对称耦合机构。首先通过互感原理得到系统传输特性方程,分析不同耦合程度下的电能传输可行性。同时,建立电磁场路耦合仿真模型,获得高铁系统实际工况下的空间磁场分布特性。为克服高铁列车运行过程中的振动影响,提高系统的能量传输稳定性和传输效率,提出集磁环结构对耦合机构进行优化,通过仿真分析并且搭建实验平台进行实验验证。结果表明集磁环结构能够有效收聚磁场,且系统在5cm传输距离下获得91.4%的传输效率。在接收线圈动态移动过程中,集磁环结构能够有效提高高铁列车的无线供电稳定性和工作效率,证明了高铁列车无线供电的可行性。Based on the dynamic coupling system of high-speed train,an asymmetric coupling system with single rectangular transmitting coil and multi-square receiving coils in series is proposed in this paper.The transmission performance of system is obtained by mutual theory,and the feasibility of power transmission is analyzed under different coupling coefficients.By the field-circuit coupled simulation,the magnetic distribution character of high-speed train system is concluded.In order to overcome the vibration influence and improve the stability of power transmission stability and system transmission efficiency,the ferromagnetic collector circles are used to optimize the receiving coils.The simulation and experiment have verified the optimized system.The results show that the ferromagnetic collector circles could gather the magnetic around the coils,and the system transmission efficiency is91.4%under5cm air gap.The stability of power supply and transmission efficiency are improved when there is an offset,and the feasibility of wireless power supply for high-speed train is verified.
