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 13):
The power transmitter of  claim 1  wherein the drive frequency adapter is arranged to adapt the drive frequency in response to the load estimate during a power transfer phase
