Simulation Analysis of Mobile Phone Wireless Charging Coupling Coil Based on Maxwell
To a large extent,the efficiency of radio energy transmission depends on the coupling coefficient of the cou-pling coil.In order to improve the coupling coefficient between the two coils,the planar coil structure commonly used for wireless charging of mobile phones was modeled.Maxwell was used to simulate and analyze the two common planar circu-lar and planar square coils.The optimal shape is selected and the inner and outer diameters,turn spacing and magnetic core of the coil with the optimal shape are simulated.The results show that the coupling coefficient of the coil can be changed by changing both the inner and outer diameters,and the influence of the outer diameters is greater.The coil with different turn spacing has different coupling coefficient,and the coil with equal turn spacing can have higher coupling coef-ficient.Coil with magnetic core can obtain higher coupling coefficient than coil without magnetic core.
