Abstract
The electric-field coupled wireless power transfer(EC-WPT)system,featured by lightweight and low-cost coupler,and minimal eddy current loss generated between or around the conductors of the couplers,is suitable for dynamic wireless charging applications for electric vehicles.This paper constructs a dynamic EC-WPT system based on a segmented coupler.Taking the dynamic EC-WPT system with double-sided LC-compensation as the object,a mathematical model of the system is established.The theoretical derivation of the system's output characteristics when its receiving plates move above the segmented guide rail,and a power supply switching strategy is proposed.With the aim of improving system transmission performance and the lateral misalignment ability of the coupler,a parameter design method for the coupler is given.A simulation model of the system is established to analyze the variation of output power during the movement of the receiving plates,and an experimental setup is built to verify the rationality of the designed system and parameter design method.The simulation and experimental results show that the variation trend of the output power of the system is consistent with the theory results when the receiving plates are in the transition area of two adjacent rails.关键词
