主 题：Wireless power transfer Magnetic coupler Simulated annealing algorithm Robust optimization
摘 要：Fleets of autonomous vehicles including shuttle buses,freight trucks,and road sweepers will be deployed in the Olympic Vil-lage during Beijing 2022 Winter *** requires intelligent charging infrastructure based on wireless power transfer technology to be *** increase the misalignment tolerance of a high-power wireless charger,the robustness of the magnetic coupler should be *** paper presents a new type of unipolar coupler,which is composed of three con-nected coils in *** dimensional configuration of the coils is analyzed by the finite element *** characteristic parameters of the coil are identified with their influence on the self-inductance and coupling *** expert model is built,whose feasibility can be verified in the aimed design *** with the expert model,an improved simulated annealing algorithm with a backtracking mechanism is *** primary coil can reach the expected characteristics from any starting parameter combination through the proposed optimization *** the same conditions in terms of external circuit parameters,ferrite usage,and aluminum shielding,the offset sensitivity of the magnetic coupler can be reduced from 58.79%to 18.89%.A prototype is established,validating the feasibility of the proposed coil structure with the optimized parameter algorithm.
