Abstract

Disclosed is a system and a method of operating an inductive power transfer system for transferring power to a vehicle. The inductive power transfer system includes a primary winding structure for generating an alternating electromagnetic field and a secondary winding structure for receiving the alternating electromagnetic field and generating an alternating current output voltage, wherein the alternating current output voltage is rectified and supplied to at least one energy storage element. The rectified output voltage is adjusted by varying a gap size of a gap between the primary winding structure and the secondary winding structure, wherein the gap size is adjusted to prepare and/or to initiate and/or to control an energy transfer process depending on charging characteristics of the at least one energy storage element.
