Wireless power transfer (WPT) has the advantages of flexibility, safety, and high reliability. Thus, it is widely used in portable electronic equipment, electric vehicles (EV), medical equipment, and other fields. The resonance compensation method of wireless charging directly affects the gain characteristics of the output current and voltage. As a result, this is one of the main research focuses of wireless power transmission technology. A new hybrid compensation topology circuit is proposed in this paper, which is based on the EV constant-current (CC) and constant-voltage (CV) charging mode. In this hybrid topology circuit, an equivalent loosely coupled transformer T model is established for the primary and secondary coils. Through an analysis of the circuit principle, it is concluded that the wireless power transmission circuit can realize CC and CV outputs under a dynamic load change. The output power efficiency characteristics of the serial/parallel (S/P) compensation and serial/serial (S/S) compensation circuits are analyzed. In addition, the mutual inductance parameters are optimized by an efficiency power product method to achieve the overall optimal parameter design in terms of the circuit output power and efficiency. A simulation model and an experimental prototype of the wireless power transmission circuit are established. The design process of the circuit parameters under a given target current and voltage is also presented. The simulation verifies the correctness of the constant current and constant voltage output of the S/P–S/S hybrid compensation circuit. The experimental platform verifies the CC output under the S/P compensation topology, and the CV output under the serial/serial (S/S) compensation topology.
