September 17, 2025
A powering apparatus (100) for wireless powering of a power receiving device (200) comprises: a plurality of power transmitters (110) configured to provide inductive coupling to the power receiving device (200); and an oscillator (130) configured to provide a reference oscillator signal; wherein each power transmitter (110) comprises an inductive element (112) and a driving circuitry (120) for providing a current signal for driving the inductive element (112), wherein the driving circuitry (120) of each power transmitter (110) is configured to receive the reference oscillator signal and a feedback signal of a current through the inductive element (112) for controlling a phase of the current signal in relation to a phase of the reference oscillator signal, each of the plurality of power transmitters (110) being configured for outputting a powering signal controlled by a common phase relation to the reference oscillator signal.
