Design and Optimization of Parameters of Electric Vehicle’S Wireless Power Transmission System to Decrease the Influence of Coexistence Interference

摘要

Electromagnetic interference has always been a significant issue in electric vehicle's(EV) wireless power transmission(WPT) system, the interference will not only bring about frequencies subject to interference to other systems, but also can produce interference to other EV's WPT system. In the past studies, the majority of system designs implement additional control means to ameliorate interference with the WPT parameters that have been designed. Therefore, this paper aims to provide some engineering reasonable design and optimization guidance through effective experiments for EV's WPT system. The paper starts with the parameters of the EV's WPT system, sets up a reasonable range of variation, analyzes the influence of many parameters on the coexistence between systems, and confirms the optimization scheme by calculating the unified evaluation criteria. At last, the design suggestions and guidance are proposed in paper.
