Abstract:
A wireless power transmitter ( 101 )) comprises a resonance circuit ( 201 ) comprises a transmitter inductor ( 103 ) for generating a power transfer signal for wirelessly transferring power to the power receiver ( 105 ). A driver ( 203 ) generates a drive signal for the resonance circuit ( 201 ) and a resonance modification circuit ( 505 ) aligns the resonance frequency of the resonance circuit ( 201 ) with the drive frequency of the drive signal by slowing a state change for resonance circuit ( 201 ) for a fractional time interval of cycles of the drive signal. A load estimator ( 509 ) generates a load estimate reflecting an equivalent load resistor for the transmitter inductor ( 103 ) reflecting the loading of the power transfer signal. A drive frequency adapter ( 511 ) then adapts the drive frequency in response to the load estimate. The invention may in particular improve load modulation communication quality.

Claim (Index 4):
The power transmitter of  claim 1  wherein the drive frequency adapter is arranged to determine an operating range for the drive frequency in response to the load estimate and to restrict the drive frequency to the operating range.
