  • 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.

  • Patent number: 8320143
    Abstract: A current-triggered synchro-rectifier comprising an electronic switch configured to be in its ON setting when the current flowing through its cathode exceeds a predetermined threshold. The electronic switch may include a half-wave rectifier wired to the source terminal and the drain terminal of a MOSFET device, and a current monitor configured to monitor the drain-current flowing through the drain terminal. The current monitor sends a gate signal to the gate terminal such that the MOSFET is switched to its ON state when the drain-current exceeds a first threshold current and the MOSFET is switched to its OFF state when the drain-current falls below a second threshold current. Usefully, the synchro-rectifier may be incorporated into a full-wave rectifier.

  • Publication number: 20120193993
    Abstract: An inductive power transfer system and method for transferring power to an electrical device wirelessly. The system includes an inductive power outlet and an inductive power receiver. During operation, instruction signals are sent from the inductive power outlet to the inductive power receiver. When no instruction signals are transferred, the system is configured to deactivate such that power is drawn by the system only during operation.

  • Patent number: 8188619
    Abstract: Non-resonant inductive power transmission wherein the driving voltage across a primary inductor oscillates at a frequency significantly different from the resonant frequency of the inductive coupling system. Embodiments of the invention include systems and methods for: power regulation using frequency control, fault detection using voltage peak detectors and inductive communication channels.

  • Patent number: 8049370
    Abstract: An inductive power transmission platform includes a plurality of inductive power outlets connected to a common driver via individual power switches. The inductive power outlets are configured to couple with inductive power receivers to provide power to electrical loads wired thereto. The switches may be configured to remain closed while current passes therethrough. The common driver may be used to manage the power drawn by the transmission platform to each of the inductive power outlets.

  • Publication number: 20100219697
    Abstract: An adjustable inductive power transmission platform includes inductive power outlets embedded into adjustable modules having multiple configurations. The inductive power outlets are configured to couple with inductive power receivers to provide power to electrical loads wired thereto. The multiple configurations of the adjustable modules allow the position of the inductive power outlets to be adjusted to match the locations of inductive receivers to suit changing requirements.
