With the development of new energy industry, lithium battery is favored by the market for its superior performance. In order to meet the actual requirement of constant current and constant voltage in the process of lithium battery charging, and to improve the flexibility and safety of charging, this paper proposes a constant voltage/constant current wireless charging system based on T/F variable structure compensation network at the transmitter side. Firstly, the basic output characteristics of S-S compensation network under different power input conditions are analyzed, and the design idea of variable structure compensation network suitable for wireless charging of lithium battery is derived based on the construction mechanism of higher-order compensation network. Secondly, the analysis models of constant voltage and constant current charging mode are established by the equivalent circuit. The basic conditions for realizing the constant output and maintaining the zero phase angle state of the system are derived, and the internal relationship between the system gain and the variable structure compensation network parameters is revealed. At the same time, the control method of switching charging mode by sampling the current of the transmitting side is given. Finally, the variable structure compensation network of the system is verified by simulation and experiment.
