Reserch on Dynamic Wireless Charging of Electric Vehicle Based on Double LCC Compensation Mode

Due to the dynamic wireless charging of electric vehicle has the characteristics of large offset and fast moving speed, the control of the system and the choice of compensation mode are more important. In view of the problem that the original side control in the dynamic wireless charging system of electric vehicles is susceptible to the change of the coupling parameters of the auxiliary side, this paper explores the transmission characteristics of double LCC compensation mode in the dynamic wireless charging system from the perspective of compensation mode. Through mathematical modeling and simulation analysis, the double LCC compensation mode not only has constant current output characteristics, but also has stronger stability for the dynamic wireless charging system of electric vehicles. Finally, the constant current output and the Strong stability characteristics of the double LCC structure are verified by comparing the electrical parameters of the double LCC structure and the traditional compensation mode applied in the dynamic wireless charging system for electric vehicles.
