In order to suppress the fast decrease of the transfer efficiency of magnetic resonance coupled wireless power transfer system (MRCWPTS) with distance increase, this paper investigates the impact factors of the system transfer efficiency and is, then formulates a new efficiency optimal control method based on frequency control. Based upon this control method two optimal control schemes are designed to achieve transfer efficiency control of the system. Simulations and experiments show that the proposed efficiency optimal control method can effectively stabilize the system transfer efficiency in a certain range so as to successfully solve the subtle issue of transfer efficiency variation with distance. magnetic coupling, frequency control, efficiency optimal, wireless power transfer Citation:Tan L L, Huang X L, Huang H, et al.
