Converters for Locomotives

KONČAR manufacture a range of electronic equipment for electric locomotives, their converters are used for supplying the main and auxiliary drives of locomotives. KONČAR's converters feature high quality, functionality and reliability combined with easy maintenance. 

KONČAR's two converters for locomotives are: KONTRAC GP 1000 AC and KONTRAC PN 170 AC

 

Propulsion Converter for Locomotives - KONTRAC GP 1000 AC

KONTRAC GP 1000 AC Converter

Thyristor propulsion converters convert AC network electric power fed from a transformer output into propulsion power for DC traction motors. The converter is used in the process of modernisation of old diode locomotives into thyristorised locomotives as well as for building new locomotives.

Replacement of diode converters with the thyristor converters and implementation of vehicle control unit for traction application (VCU) ensures conversion of old diode locomotives to modern thyristor locomotives with superior traction and exploitation characteristics.

Auxiliary Converter for Electric Locomotives - KONTRAC PN 170 AC

KONTRAC PN 170 AC Converter

This converter is fed from a dedicated winding of the main transformer, converts single-phase voltage into three-phase stabilised voltage and supplies electrical loads such as traction motor blowers, brake resistor blowers, transformer oil cooler blowers, pump, compressors and HVAC. The battery charger is an integral part of the converter, is used for charging locomotive batteries and supplying of all DC consumers on board the vehicle.
