This paper points out that in the process of charging batteries,wireless energy transmission systems need to control appropriate charging voltage and charging current to achieve high charging efficiency and protect the battery.Therefore,this paper proposes a method of adjusting the output voltage and current of the secondary side by controlling the flux controllable inductance on the primary side of the wireless energy transmission system.This paper firstly designs the topology structure of the system and analyzes the relationship between adjustable inductance,charging voltage,and current;secondly,the anti offset performance of the system is analyzed,and the parameters of the transmission coil are optimized through orthogonal experimental method to make the system have good anti offset performance;finally,a fuzzy PI controller is used to accurately control the charging voltage and current,and a detailed analysis is conducted based on the results of PLECS simulation.
