Parameter Matching Method of LCC/S for Compensating Dynamic Wireless Power Transfer System

Dynamic wireless power transfer (DWPT) realizes a reliable power transmission between relatively moving objects. In this paper, a parameter matching method based on particle swarm optimization (PSO) algorithm is proposed to design the parameters of the LCC/S compensation topology using for an unmanned vehicle DWPT system. Firstly, the mathematical model of the LCC/S compensation topology is derived, and then three factors that affect the transmission characteristics of the system in the resonant state are analyzed. Then, the principle of PSO algorithm and the general steps of parameter matching using PSO algorithm are introduced. Simulation experimental results show that the proposed method can realize the parameter design under system constraints, and realize the dynamic wireless power transfer with the transmission power of 19.73kW and the efficiency of not less than 98%.
