Abstract
An electric device for compensating common mode interference in an electric machine includes at least one compensation network with at least one compensation winding and at least one compensation capacitor. The compensation winding and the compensation capacitor are arranged in a series circuit. The at least one compensation winding interacts with at least one stator winding of the electric machine in such a way that a compensation current counteracting the common-mode interference is generated.

An electrical device for compensating for common-mode interference in an electrical machine, the device comprising:
- at least one compensation network with at least one compensation winding and at least one compensation capacitor, the compensation winding and the compensation capacitor being arranged in a series circuit, and the at least one compensation winding interacting with at least one stator winding of the electrical machine so that a compensation current counteracting the common-mode interference is generated,
- wherein the at least one compensation winding comprises a number of turns that corresponds to a number of turns of the at least one stator winding.
An electrical device for compensating for common-mode interference in an electrical machine, the device comprising:
- at least one compensation network with at least one compensation winding and at least one compensation capacitor, the compensation winding and the compensation capacitor being arranged in a series circuit, and the at least one compensation winding interacting with at least one stator winding of the electrical machine so that a compensation current counteracting the common-mode interference is generated,
- wherein the at least one compensation winding is formed together with the at least one stator winding in a manner of a one-to-one transformer.
