Beschreibung
Zusammenfassung:	The invention relates to converter technology and is intended for use as a traction converter in alternative current locomotives. The technical result is an increase in the power factor, and smooth regulation of the voltage in commutator motors in traction and regenerative-braking modes. A traction converter of a locomotive is connected to a traction transformer and comprises a controllable bridge which is connected to a section of a secondary winding of the traction transformer, and diode arms which are connectable to the remaining outputs of the secondary windings of the traction transformer via a set of contactors , forming n regulation zones. In traction mode, a commutator motor is a load; in regenerative-braking mode the commutator motor is a generator, in which power is supplied independently to an excitation winding from an excitation rectifying unit.
