摘　　要：针对无人机无线充电平台的感应耦合电能传输(ICPT)系统要求,对其补偿网络工作模式及参数设计进行了研究,提出了一种实现原边线圈励磁电流恒定、负载端恒流输出的参数设计方法。通过发射端励磁电流恒定特性、接收端恒压输出特性、接受端恒流输出特性等约束条件,分析双LCCL谐振补偿电路原边恒流副边恒压与原边恒流副边恒流两种模式的工作特性,得出在产生横向偏移时原边恒流副边恒流模式能够保持其工作模式。根据无人机降落在无线充电平台易产生横向偏移的特点,选择原边恒流副边恒流的工作模式进行Simulink仿真与样机开发,证明了不同无人机或无人机降落产生横向偏移导致互感的改变不影响系统工作状态,验证了此参数设计方法在无人机无线充电平台应用的准确性与有效性。For the requirement of Induction Coupled Power Transmission(ICPT)system on wireless charging platform of Unmanned Aerial Vehicle(UAV),the working mode and parameter design of compensation network were studied,moreover,a parameter design method was proposed to realize constant excitation current of the primary side coil and constant current output of the load side. Based on the constraints of constant excitation current at the transmitter,constant voltage output at the receiver and constant current output at the receiver,the working characteristics of two modes of double Inductance-Capacitance-Capacitance-Inductance(LCCL)resonant compensation circuit,including constant current at the primary side constant voltage at the secondary side mode;and constant current at the primary side-constant current at the secondary side mode,were analyzed. It was concluded that the constant current at the primary side and constant current at the secondary side mode can maintain its working condition when lateral offset occurs. According to the lateral offset of UAV landing on the wireless charging platform,Simulink simulation and prototype development were carried out by choosing the working mode of constant current at the primary side and constant current at the secondary side. It was proved that the change of mutual inductance caused by the lateral offset of different UAV or UAV landing did not affect the working state of the system,and the accuracy and effectiveness of this parameter design method in the application of UAV wireless charging platform was verified.
