摘　　要：针对感应耦合电能传输(Inductive Coupled Power Transfer,ICPT)系统应用场景中的信号反向传输需求,提出了一种基于LCL-S谐振拓扑的注入信号式ICPT电能信号共享通道系统。运用交流阻抗法对所提出的系统的电能通道与信号通道分别进行了理论分析,建立了数学模型。以负载得到的电压恒定为前提,兼顾信号调制解调结构的影响,分析计算了系统参数,并搭建了MATLAB/Simulink验证模型。仿真结果表明,信号传递电路引入后,负载可以实现恒压,系统能量传输正常,在保证能量传输的情况下,可以实现信号的反向传输。最后按照仿真模型搭建了实际电路,验证了所提出的系统的可行性。In order to meet the requirement of signal reverse transmission in the application scenario of inductive coupled power transfer(ICPT) system, a signal-injected ICPT power-signal sharing channel system based on LCL-S resonance topology is proposed.The power channel and signal channel of the proposed system are theoretically analyzed by using AC impedance method, and the mathematical model is established.The system parameters are analyzed and calculated based on the premise that the voltage obtained at the load is constant, and the influence of the signal modulation and demodulation structure is taken into account.A Simulink verification model is built in MATLAB.The simulation results show that after the signal transmission circuit is introduced, the load can achieve constant voltage and the system energy transmission is normal, under the condition of ensuring energy transmission, the reverse transmission of the signal can be realized.Finally, the actual circuit is built according to the simulation model to verify the feasibility of the proposed system.
