Abstract: An inductive power outlet for providing power to an electric load via an inductive power receiver includes at least one primary inductive coil wired to a power supply via a driver configured to provide a driving voltage across the primary inductive coil such that a secondary voltage is induced in a secondary inductive coil associated with the inductive power receiver. The driver may include a controller configured to receive feedback control signals from the inductive power receiver indicating if more or less power is required. The controller may be further configured to adjust the driving voltage according to the control signals.

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.

Abstract: An inductive power outlet operable to transfer power to an inductive power receiver includes a driver wired to a primary inductive coil and operable to provide a driving voltage across the primary inductive coil. The primary inductive coil is configured to form an inductive couple having a characteristic resonant frequency with at least one secondary inductive coil wired to an electric load, the secondary inductive coil being associated with the inductive power receiver. The driving voltage oscillates at a transmission frequency substantially different from the characteristic resonant frequency of the inductive couple.
