Abstract
An inductive power transfer system operable in a plurality of modes comprising an inductive power transmitter capable of providing power to the inductive power receiver over an extended region. The system may be switchable between the various modes by means of a mode selector operable to activate various features as required, such as: an alignment mechanism a resonance tuner, an auxiliary coil arrangement or a resonance seeking arrangement. Associated methods are taught.
