摘要 作为连接线圈与激励源和负载的桥梁,补偿网络是磁耦合谐振式无线充电系统中非常重要的环节。本文提出一种基于双边LCC谐振补偿网路的参数设计方法,首先对双边LCC谐振拓扑进行理论分析,推导得出输出电流和等效阻抗的表达式;其次深入分析高次谐波对谐振条件的影响,得出谐振条件;然后将电容耐压与系统等效阻抗设定在一定范围内,并通过仿真逐步确定谐振拓扑补偿电容参数的范围;最后实现电动汽车无线充电系统谐振补偿网络参数的优化。

Abstract:The resonant compensation network plays an important role in magnetically coupled resonant wireless charging system, bridging the coil and the excitation source as well as the coil and the load. This paper proposes a parameter design method based on bilateral LCC resonance compensation network. Firstly, the resonant topology of bilateral LCC is theoretically deduced, and the expressions of output current and equivalent impedance are given respectively. Secondly, the resonant condition is obtained by analyzing the influence of high-order harmonics on the resonant condition; then the capacitor withstand voltage and the equivalent impedance of the system place restrictions on a certain range. Finally, resonant compensation network parameters of the wireless charging system is optimized.
