Abstract 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 is 91.4% under 5cm 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.
