When the coils of wireless power transmission system based on a traditional topology is physically offset, the coupling coefficient between the coils will change significantly, which further leads to drastic changes in the output power of the system. This problem limits the application and promotion of wireless power transmission. In order to solve the problem of output power imbalance caused by coils' offset, this paper takes the wireless power transmission system of LCC-S type as an example, and proposes an optimization scheme for anti-offset performance based on the optimization design of compensation topology parameters. This scheme uses two freely adjustable variables K<sub>1</sub> and K<sub>2</sub> to optimize the design of the compensation network parameters of the wireless power transmission system, so that the system can automatically adjust the transmit current of the primary coil to maintain relatively stable output power. Finally, we build a 120W experimental prototype. When the lateral offset percentage &#x03B4; of the coil is less than 35%, the maximum fluctuation rate of the output power of the system is kept within 10%, and the efficiency of the whole machine is kept above 81%.
