Abstract
A power transmitter for wirelessly providing power to a power receiver comprises an output circuit comprising a transmitter coil generating a power transfer signal when a drive signal is applied to the output circuit. A load function circuit determines a load function that describes a dependency of a loading of the drive signal by the output circuit on a frequency of the drive signal for the power transmitter and power receiver arrangement. An interval circuit determines two operating frequency ranges separated by a non-operating frequency range in response to the load function. A power controller controls a power level of the power transfer signal by adjusting the frequency of the drive signal over at least frequencies within the operating frequencies while excluding frequencies within the non-operating frequency range.
