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.

A transmission device () for a vehicle with an electric machine () that is arranged in a housing () is described. The electric machine () can be placed in active connection with a rotating component () that can be guided in the power flow of the transmission device such that a level of torque that can be generated by the electric machine () can be transmitted to the component (). At least one electric component (Y) that comprises power electronics for the electric machine () is arranged in a cross-sectional area inside the housing () that is perpendicular to the longitudinal axis of the electric machine () and is located directly adjacent to the electric machine ().

Transmission device for a vehicle

The objective of providing a circuit arrangement for the control of at least one electric machine (), which is suitable for also enabling operating conditions of the electric machine () that demand high power-peaks of short duration, is essentially achieved in that the electric machine () can be connected via a DC/AC converter () and at least one switching device () to at least two different electrical energy storage devices (I, II), one storage device (I) being designed as a storage device for comparatively long-lasting power demands and the other storage device (II) as a storage device for short and high power-peaks.
