Abstract
To enhance transmission performance, a novel three-coil wireless power transfer system is proposed in this work. Unlike the traditional system in which three coils are resonant, the coils in the proposed system are hybrid resonant. According to theoretical calculation, it is found that output power is dependent on resonant frequency of the transmitting coil and the relay coil once the receiving coil is set to resonate at the operating frequency. Simulation work is conducted. Under various distance between transmitting coil and relay coil, resonant frequency of the two coils at which the output power is maximized is obtained. Compared with the traditional resonant system, the simulation result shows that output power of the proposed hybrid resonant system is higher especially at smaller distance. For further validation, experiments have been carried out which verify that better performance can be realized with the proposed hybrid resonant system.
