An incoming feeder circuit, for a multi-system traction locomotive, has at least one four-quadrant controller (8) which is connected across an intermediate (link) circuit (9) and at least one pulsed inverter (10) which drives at least one drive (11) o the multi-system locomotive. In direct current (DC) drive, the inverter (10) is driven directly via a mains filter reactor with DC traction wire (5) and in AC drive the four- quadrant controller (8) is driven via a transformer (3) with the stray inductance from the AC-traction wire (1). An auxiliary reactor (4) can be switched via a switching device such that it is switched into DC drive between the DC-tract wire (5) and the pulsed inverter (10) as a mains reactor and can be switched into AC drive in series with the secondary winding of the transformer (3) as stray inductance. |
