Abstract：The soft switching characteristics of the bilateral LCC inductively coupled wireless power transmission system are susceptible to system parameter disturbances. In order to improve the stability of the zero-voltage soft switching of the system, the system equivalent input impedance angle model and efficiency model are derived. Then, the disturbance analysis of the system's multi-topological parameters is carried out, and the influence of load changes on the system's equivalent input impedance angle and efficiency is studied. The key parameter configuration method is proposed. Finally, a test prototype with a working frequency of 86kHz, an output power of 2kW and a transmission distance of 15cm was built to verify the correctness of the theory. Simulation and test results show that the method in this paper has good load adaptability..
