Embodiment Construction

[0104] In the following, the same reference numerals denote elements with the same or similar technical features.

[0105] figure 1 A schematic plan view of the circuit arrangement 1 with the winding structure 2 is shown in the second operating mode. The winding structure 2 comprises a first sub-winding 2a and a second sub-winding 2b. The sub-winding structures 2a, 2b may be electrically connectable or electrically isolated from each other. The first and second sub-windings 2a, 2b have a rectangular shape. However, this is not mandatory by design. Each of the first and second sub-windings 2a, 2b provides a coil in which the number of turns is equal to or greater than one. The first sub-winding structure 2a encloses the first inner region A_2a. The second sub-winding structure 2b encloses the second inner region A_2b.

[0106] Also shown is the longitudinal axis x oriented parallel to the longitudinal axis of the winding structure 2 . A longitudinal axis x connects the g...

Abstract

A circuit arrangement for a system for inductive power transfer and a method of operating a circuit arrangement, wherein the circuit arrangement (1 ) comprises at least one winding structure (1 ) witha first and at least one other subwinding structure (2a, 2b), wherein the subwinding structures (2a, 2b) are operatable in a first operational mode and a second operational mode, wherein an unipolaralternating electromagnetic field is providable in the first operational mode and a multipolar electromagnetic field is providable in the second operational mode.

Description

technical field [0001] The invention relates to a circuit arrangement and a method of operating a circuit arrangement of a system for inductive power transmission. Background technique [0002] Electric vehicles, in particular rail vehicles, and / or road vehicles, can be operated on electrical energy transferred by means of inductive power transfer. Such a vehicle may comprise a circuit arrangement which may be or part of a traction system of the vehicle, said circuit arrangement comprising receiving means adapted to receive an alternating electromagnetic field and generate an alternating current by electromagnetic induction. In addition, such a vehicle may include a rectifier adapted to convert alternating current (AC: alternating current) into direct current (DC: direct current). DC can be used to charge the traction battery or to run the electric motor. In the latter case, the DC can be converted to AC by an inverter. [0003] Inductive power transfer is performed using...
