The device has a multilevel converter (5) with a common neutral point (7) connected with a neutral point (12) of a filter circuit (8) and a neutral point (15) of a zigzag winding (14) attached to phases (3) of a current system (2). The common point is connected with the phases over the circuit and the winding such that a low impedance connection of the common point with the phases is provided relative to a null current of the current system and a high impedance connection of the common point with the phases is provided relative to positive sequence of the current system.
