method for operating an inductive power transfer system, and, inductive power transfer system.

摘要

The invention relates to a method of operating an inductive power transfer system (1) for transferring power to a vehicle, wherein the inductive power transfer system (1) comprises 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 (12), wherein the rectified output voltage (uc) is adjusted by varying an air gap size of an air gap between the primary winding structure and the secondary winding structure, wherein the air gap size is adjusted to prepare and / or to start and / or to control a power transfer process depending on charging characteristics of at least one storage element d and energy (12). Additionally, the invention relates to an inductive power transfer system for transferring power to a vehicle.
