摘要： 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.

摘要： A system and method for inductively providing electrical power at a plurality of power levels to electrical devices. The system may include an inductive power outlet unit conductively coupled to a power supply and an inductive power receiver unit associated with the electrical device. The inductive power outlet unit includes a driver device operable to generate power at a plurality of power levels and electrical power is transferred to the electrical device at a power level selected from the plurality of power levels, in accordance with electrical power requirements of the electrical device. The power receiver may be operable in a plurality of modes having a secondary inductor configured to operate selectively with a plurality of inductance values.

摘要： An inductive power transfer system and methods for controlling efficient operational wireless power transfer to an electrical device. The system includes an inductive power outlet, an inductive power receiver and a signal transfer system communicating power transfer instruction from receiver to outlet, while transferring power from the outlet to the receiver. The present invention relates to wireless power transfer systems and methods incorporating a current limiter activation mechanism to allow power transfer at an extended operational range, providing a technical solution when an inductive power outlet and an inductive power receiver are laterally misaligned.
