Abstract：Aiming at the volatility of transmission efficiency and receiving current between the power coupling mechanisms in the dynamic wireless power supply system of electric vehicle,this paper derives the transfer efficiency function of the system,and the relationship between the original coil current and the system switching control is obtained by analyzing the control mode. Then, a transmitter control strategy with self - detecting step - switching function and vehicle-mounted three coil receiving structure are presented. Finally, a 5kW dynamic wireless power supply system simulation platform is built. It is proved by experiments that this structure can effectively reduce the fluctuation of the system transmission efficiency and the receiving current.
