Abstract
A wireless electric energy transmission system is provided, including a transmitter and a receiver. The transmitter includes a DC/AC inverter circuit, a first inductor, and a first capacitor that are connected in series. The transmitter is configured to: detect a value of a resonant frequency of the transmitter; detect a value of a coupling coefficient between the transmitter and the receiver; obtain a value of a constant-voltage operating frequency of the transmitter through calculation based on the resonant frequency and the coupling coefficient; and control an operating frequency of the DC/AC inverter circuit based on the constant-voltage operating frequency obtained through calculation.
