Auxiliary converter for electric locomotives


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