Abstract:In order to solve the problem of difficult implement of synchronization of maximum transfer efficiency and power in wireless power transmission system via magnetic resonance coupling,the power transmission system was analyzed by equivalent circuit theory,and the calculation method to optimal frequency of transfer efficiency and its power was proposed.The concept of optimal resonance frequency and power-efficiency synchronization factor was presented,and the synchronous condition to maximum transfer efficiency and power was given.By simulating,the varying regularity of the transfer efficiency and power with load changes was researched.The experimental platform was set up and the correctness of the theoretical analysis is proved by comparing the simulation results and measured data.Thus provides an useful reference for the further optimization of power-efficiency synchronization and the improvement of transfer efficiency and its power in wireless power transfer system.
