摘　　要：高效性和紧凑性是电动汽车无线充电的两个重要指标,双端LCC补偿网络为无线充电系统提供了一种高效补偿方式,但两个谐振电感导致系统体积和电磁干扰增大,限制了该方法在动态无线充电系统中的使用。为解决该问题,本文提出一种新型集成式电磁耦合机构,将谐振线圈集成到主线圈上,利用3D有限元分析工具ANSYS Maxwell对新型电磁耦合机构进行优化,给出可提供系统高效率的耦合线圈的标准化设计与优化过程。本文在4. 8kW动态无线充电实验平台上,对比分析非集成式动态无线充电系统和集成式动态无线充电系统,验证了新型集成式耦合机构在效率、体积、磁场屏蔽方面具有更大优势。High efficiency and compactness are two important indicators for wireless charging of electric vehicles.The double-sided LCC compensation network provides an efficient compensation method for wireless charging systems. However,two resonant inductors will cause a large increase in system volume and electromagnetic interference,which limits the use of this method in dynamic wireless charging system. To solve this problem,a new type of integrated magnetic coupler is proposed,which integrates the resonant coil into the main coil. Using the 3 D finite element analysis tool Ansys Maxwell to optimize the new integrated magnetic coupler,the standardized design and optimization process of the coupled coils which can provide high efficiency for the system is given. In this paper,the non-integrated dynamic wireless charging system and the integrated dynamic wireless charging system are compared and analyzed on the 4. 8 kW dynamic wireless charging experiment platform. It is proved that the new integrated magnetic coupler has greater advantages in efficiency,volume and magnetic field shielding.
