AUXILIARY CONVERTER GTO BASED 3 × 100KVA

for Electric Locomotives

Compliant Standards: IEC 61287-1, IEC 60571 and IEC 60310.

 

 

  • A modular concept, in which, each module serves a specific power and control function.
  • Designed to give 200 kVA with VVVF and 100 kVA with VVCF.
  • Designed to sustain wide input voltage and frequency variations.
  • Thyristor controlled rectifiers.
  • Independent phase modules of inverter combined to build a 3-phase inverter.
  • Protection against over voltages in the DC link and at the input.
  • Microprocessor based electronic rack for controlling and monitoring the functioning of the power modules.
  • Communication between converter and the vehicle control unit through MICAS-52.
  • Cooling within the cubicle through internal fans.
  • Easy to maintain and lower life cycle cost.
