The resonant frequency of resonant wireless power transmission is high and the power electric device is difficult to achieve high-frequency high-power switching converters at present. Accordingly, a method for reducing the resonant frequency of resonant wireless power transmission was proposed based on fractional-order principle. The circuit model of series-series fractional-order wireless power transmission system was then established, and the output power and transmission efficiency were deduced. The influence of the fractional order on the parameters and characteristics of resonant wireless power transmission was analyzed by Matlab simulation. The results show that the fractional-order inductance and capacitance components can greatly reduce the resonant frequency of resonant wireless power transmission and the switching frequency of the switching device, and can also output more power than the integer order wireless power transmission system.
