Electromagnetic Induction Wireless Power Transmission Efficiency Research
Using the theory of mutual inductance coupling theory and establish mathematical model for the coupling coil wireless charging, is obtained by analyzing the key factors influencing the electromagnetic induction wireless power transmission efficiency: two coil radius relative position and relative size, coil, coil number of turns, working frequency and load, etc. Then by using Maxwell's software control variable method is used to simulation analysis was carried out on the key factors. According to the simulation results, summed up the method of improve the efficiency of the wireless charging equipment transmission.
