The invention discloses a non-contact electrical energy transmission device with self-adaptive power factor correction and a control method, the device adopts the AC (alternating current)/DC (direct current)/AC (alternating current) energy conversion way, the structure of a diode rectifier bridge plus a half-bridge double-switch is used for realizing the functions of active power factor correction and resonance inversion, and the structure of a three-order resonant network is further utilized for realizing the functions of reactive power compensation and load self-adaption. The control method of the device is simple, and only a driving signal with a constant frequency and constant duty cycle needs to be imposed on the half-bridge double-switch. The problems of small output power, great harmonic pollution, poor load applicability and the like in the non-contact electrical energy transmission technology can be solved by the device and the control method, and the device and the control method can be widely used in moving and lifting equipment of plants, mining and transporting equipment of coal mines, electrical power and subway locomotives, factories and mines with flammable and explosive gas and other various occasions.
