摘　　要：针对电动汽车无线充电技术中电池充电时的负载变化范围大,而单一的拓扑难以满足系统对负载全变化范围内的高效率要求这一关键问题,此处提出一种新颖的电动汽车高效感应耦合充电系统,其结合了两种不同拓扑对负载变化情况下的系统高效率优势,旨在为电动汽车无线充电技术提供理论支撑,也为高效感应耦合电能传输系统设计方法提供参考方案。首先进行了理论推导,得出了模式切换的阈值,然后在此基础上进行了实验验证。实验结果表明所提新型电动汽车感应耦合充电系统能够满足变负载条件下高效率的要求。In the wireless charging technology of electric vehicle when the battery is charged,the range of load changes is large.However,a single topology is difficult to meet the key issue of high efficiency requirement in the whole range of the load.A novel high efficiency inductively coupled charging system that combines the advantages of two different topologies for system efficiency under load variations is proposed to provide theoretical support for wireless charging of electric vehicle and a reference solution for the design of highly efficient inductively coupled power transfer systems.The .theoretical derivation is firstly carried out,the threshold of mode switching is obtained,and then on this basis,the experimental verification is done.The experimental results show that the new proposed electric vehi- cle inductively coupled charging system can meet the high efficiency under variable load conditions.
