摘　　要：本文优化基于Class-E^(2)无线电能传输(WPT)的平面电感;由于平面电感的连接方式不同,其电感的磁芯损耗和铜损也会不同,因此提出了平面电感四种优化方法,并以利兹线电感作为对照组,分析得出最小损耗连接方法;在此基础上,搭建基于推挽式Class-E逆变器和Class-E整流器的无线电能传输系统;实验结果表明,平面电感采用交错排列方式的磁芯损耗最小,可使Class-E^(2)无线电能传输系统在48V,203W输出时效率达到86.4%。This paper optimizes the planar inductor used in Class-E2 based wireless power transfer(WPT).Different constructions of the planar inductor will change parameters of inductor,such as core loss and copper loss.Four types of connection methods of the planar inductor are proposed and being analyzed to get the loss-minimum one.At the same time,a Litz-wire inductor is set as a control group.In the experiment,the Class-E2 based on the WPT system with push-pull Class-E rectifier and inverter is set up and compares the performance of it with planar inductors and Litz-wire inductor mentioned before.By using the planar inductor with the proposed interleaved arrangement,the efficiency of the Class-E2 based WPT system reaches 86.4%at the output of 48V,203W.
