Abstract In order to solve the problem that the received power of load decreases with distance decreasing in wireless power transfer system via coupled magnetic resonances in the over coupled regime, this paper presents a new model that yields critical insight into the design of practical systems. The quantitative relationship between the received power of load and input impedance is introduced to improve the transfer power ultimately. Finally, simulations and experiments were implemented to verify the correctness of the mechanism and the effectiveness of the method. The results of simulations and experiments were well consistent with the theoretical analysis.

Key words： Wireless power transfer coupled magnetic resonances power decreasing impedance mismatch
