Design and Research of Main-auxiliary Cooperative Receiving Coil for Dynamic Wireless Charging
摘要
Abstract
Based on the time-sharing working principle,a main-auxiliary(MA)cooperative receiving coil with a lower space occupation rate and a simple control is proposed in this paper,which can effectively improve the anti-misalign-ment capability of a dynamic wireless charging(DWC)system.First,the structure and circuit topology of the MA coil are designed,and the two auxiliary coils are connected in reverse series and symmetrically placed on both sides of the main coil.Second,the output performance of the MA-coil in the y-direction is calculated based on the time-sharing working principle,and the auxiliary coil only works and enhances the total output power when the misalignment occurs.Third,the most suitable ratio of wM to wA is determined through simulations,and the effective misalignment range and anti-mis-alignment capability are compared between the MA and square coils in this case.Finally,an experimental prototype was built,and it was found that the effective misalignment range of the MA coil reached 0.183τ,which is 23%higher than that of the square coil of the same size.关键词
