Abstract
This application provides a wireless power transmission system. The system includes a transmitter and a receiver, where the transmitter includes a DC/AC inverter circuit, a first resonant inductor, a first capacitor, and a first compensation inductor that are connected in series; and the receiver includes an AC/DC rectifier circuit, a second resonant inductor, a second capacitor, and a second compensation inductor that are connected in series; and power at the transmitter is transmitted to the receiver through electromagnetic induction between the first resonant inductor and the second resonant inductor, and the AC/DC rectifier circuit is configured to provide the rectified power to a load of the receiver. This solution is applicable to a wireless power supply scenario or a wireless charging scenario.
