摘　　要：提出了一种用于无线充电系统的S-S/LCL-S型复合补偿网络及其充电控制方法。S-S/LCL-S型补偿网络具有输出负载无关特性,补偿网络能够实现恒流(Constant Current,CC)/恒压(Constant Voltage,CV)输出[1,2]。在实现CC/CV充电的功能上,提出了一种适用于复合补偿网络的充电控制方法。控制方法通过无线通信的方式控制两个DC-DC变换器即可同时实现CC/CV充电和传输效率的优化。最后,通过仿真验证了复合补偿网络的输出特性及充电控制方法的可行性。This paper proposes a S-S/LCL-S composite compensation network and its charging control method for wireless charging systems.The S-S/LCL-S type compensation network has output load-independent characteristics,and the compensation network can achieve Constant Current(CC)/Constant Voltage(CV)output.In the realization of the CC/CV charging function,this paper proposes a charging control method suitable for the compound compensation network.The control method can control two DC-DC converters by means of wireless communication to realize the optimization of CC/CV charging and transmission efficiency at the same time.Finally,the full text verifies the output characteristics of the composite compensation network and the feasibility of the charging control method through simulation.
