Abstract: A power transmitter (101) wirelessly provides power to a power receiver (105) via a power transfer signal. A driver (201) generates the power transfer signal to employ a repeating time frame comprising a power transfer time interval and a communication time interval. A communication unit (205) and power transfer coil (103) communicate with the power receiver (105) using modulation of the communication carrier signal during communication time intervals. A transition controller (209) controls the drive signal to perform a power level transition between a higher power level during a power transfer time interval and a lower power level of a communication time interval closest to the power transfer time interval. An adapter (211) adapts a rate of change, a duration and/or a transition profile of the power level transition in dependence on a power level operating point for the power transfer. For example, faster transition may be performed at lower power transfer levels than at higher power levels.
