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.
