AUXILIARY CONVERTER GTO BASED 3 × 100KVA
for Electric Locomotives
Technical Features
- 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.
Applications
Converts single phase input voltage with typical railway characteristics to stabilised 3-phase voltages for the safe and reliable operation of electrical equipment onboard railway vehicles.
