Compensation network
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.
Inductive-capacitive filters and associated systems and methods
An inductive-capacitive filter includes a first insulating-conductive strip wound around a winding axis, where the first insulating-conductive strip includes a first conductive strip joined with a first insulating strip. An inductive-capacitive filter assembly includes a first and a second insulating-conductive strip concentrically wound around a winding axis, the first insulating-conductive strip including a first conductive strip joined with a first insulating strip, and the second insulating-conductive strip including a second conductive strip joined with a second insulating strip.
Electrical circuit device for operating an externally excited electrical machine, electrical drive apparatus, and motor vehicle
An electrical circuit device for operating an externally excited electrical machine includes an exciter circuit, an inverter circuit, a capacitor, and a support structure. The exciter circuit includes at least one exciter circuit module arranged on a first side surface of the support structure. The at least one exciter circuit module includes at least one direct current terminal that is connected directly to a terminal of the capacitor.
