Wireless power transmission system for realizing resonance tracking through low-frequency pulse control

The invention belongs to the technical field of wireless power transmission, and particularly relates to a wireless power transmission system for realizing resonance tracking through low-frequency pulse control. Comprising a power supply, a transmitting end and a receiving end, the transmitting end is provided with a compensating circuit formed by a resonant capacitor and a transmitting coil which are connected in series, and the receiving end is provided with a receiving coil; the transmitting end further comprises a bridge inverter. According to the wireless electric energy transmission system, resonance tracking is completed through low-frequency pulse control of the inverter, and self-oscillation of current is achieved through pulse charging of voltage. Compared with a traditional method for achieving self-oscillation through negative resistance, additional complex negative resistance design is not needed, only inverter control signals need to be changed on the aspect of achieving self-oscillation, theref
