More Information
Summary:Various embodiments may provide a transmitter device. The transmitter device may include an oscillator configured to operate at a variable oscillation frequency to generate an oscillator signal. The transmitter device may also include a transmitter antenna configured to transmit power to a receiver device via magnetic coupling based on the oscillator signal. The transmitter device may further include a feedback arrangement configured to generate a feedback to the oscillator based on a resonant frequency of the magnetic coupling between the transmitter antenna and a receiver antenna of the receiver device such that the variable oscillation frequency of the oscillator is adjusted towards the resonant frequency.
