随着无线能量传输技术的不断发展,无线充电技术逐渐进入人们视野。该文对无线能量传输技术理论进行分析,对高阶补偿网络S-LCC(一次侧串联补偿二次侧LCC补偿)谐振补偿网络,以及S-LCL(一次侧串联补偿二次侧LCL补偿)谐振补偿网络进行理论分析。在理论分析基础上,对2个高阶补偿网络的参数进行设计和仿真分析。仿真结果表明:S-LCC谐振补偿网络具有恒压输入—恒流输出特性,S-LCL谐振补偿网络具有恒压输入—恒压输出特性,且设计的无线充电系统耦合变压器补偿谐振网络参数,符合电动汽车无线充电系统设计要求。

With the continuous development of wireless energy transmission technology,wireless charging technology has gradually entered people’s field of vision.In this paper,the theory of wireless energy transfer technology is analyzed,and the resonance compensation network of S-LCC(primary side series compensation and secondary side LCC compensation)and S-LCL(primary side series compensation and secondary side LCL compensation)resonance compensation network are analyzed theoretically.On the basis of theoretical analysis,the parameters of two higher-order compensation networks are designed and simulated.The simulation results show that the S-LCC resonant compensation network has the characteristics of constant voltage input and constant current output,and the S-LCL resonant compensation network has the characteristics of constant voltage input and constant voltage output,and the designed wireless charging system couples transformer to compensate the resonant network parameters,which meets the design requirements of the wireless charging system of electric vehicles.
