Abstract
An inductive power transfer system is provided that includes at least one inductive power receiver having at least one secondary inductor for forming an inductive couple with a primary inductor and providing power to an electric load and at least one inductive power outlet having at least one primary inductor wired to a power supply via a driver configured to provide a driving voltage across the primary inductor. The driving voltage is oscillating at a transmission frequency significantly different from the natural frequency of the inductive couple. The system further includes at least one power monitor and at least one frequency modulator operable to adjust the natural frequency of the inductive couple thereby regulating power provided to the electric load.
