Abstract: The device has a drive unit coupled to a generator and connected via a rectifier to a d.c. intermediate circuit, a static converter connected to the intermediate circuit with multiple a.c. output connections and a filter arrangement connected to the a.c. output connections. The filter arrangement has series filter inductances per output and a filter capacitance connected to their junction. The filter capacitors are connected to a star point. The device has a drive unit coupled to a generator (1) and connected via a rectifier (2) to a d.c. intermediate circuit (3), a static converter (4) connected to the d.c. intermediate circuit with multiple a.c. output connections (5) and a filter arrangement (6) connected to the a.c. output connections. The filter arrangement has a first filter inductance (7) per a.c. voltage connection, a second filter inductance (8) in series and a filter capacitance (9) connected to their junction. The filter capacitors are connected to a star point (10).
