Optimization Design of Coupling Mechanism of Wireless Power Transfer System Based on LCC / S Topology

In order to optimize the wireless power transfer (WPT) system and design the coupling mechanism reasonably, this paper first analyzes the system efficiency and compensation capacitance voltage characteristics under LCC/S compensation topology, and then explores the shielding principle of ferromagnetic materials and metal materials and the influence on the coupling mechanism parameters. Based on the analysis of the number of turns and the dimension of coils, a design scheme that meets the requirements is designed for the 30kW electric vehicle.
