  • Publication number: 20130049482
    Abstract: An inductive power receiver provides a regulated power output to an electric load. The receiver inductively couples with an inductive power transmitter to form an inductive transfer system. A receiver-side regulator is provided to regulate the output voltage of the inductive transfer system. The regulator has a resonance-altering component and a switching unit configured to selectively connect the resonance-altering component to the reception circuit such that the amplitude of the induced voltage is controlled.
