Abstract
In the wireless charging process of electric vehicle using inductive coupling electric energy transmission technol-ogy,the mutual inductance of the energy pickup coil inside the vehicle decreases during the turning process.This paper proposes to use the embedded circular coil to compensate.The optimal turns and unified specification parameters of the compensation coil are obtained through genetic algorithm,theoretical derivation and simulation verification.By building the COMSOL Multiphysics platform,MATLAB/Simulink platform combined with the simulation platform and the physical experiment platform,the experimental data shows that,the embedded circular coil is used to compensate when turning,and the mutual inductance fluctuation remains about±0.4％.Due to the stability of mutual inductance fluctuation,the voltage fluctuation of energy pickup system of electric vehicle is 3.6％after optimization compensation.关键词
