摘要：
Aiming at the problems of small transfer distance, large inductance and low transfer efficiency of the traditional electric-field coupled wireless power transfer (EC-WPT) system, a parameter design method of complementary symmetry LCC resonant is introduced in this paper based on an EC-WPT system with double-sided LC network. Taking the transfer efficiency as the objective function, an adaptive genetic algorithm with nonlinear programming is proposed to optimize the system frequency f and the ratio of the parallel resonant capacitor to the coupling capacitance k. Combined with the parameter define method, a set of system parameters that can satisfy zero phase angle (ZPA), low excitation voltage and small inductance are obtained under a certain transmission distance. The transfer efficiency is maximized when the system meets the required output power. The simulations and experiments verify the feasibility and effectiveness of the proposed optimization method. © 2019, Electrical Technology Press Co. Ltd. All right reserved.
