This System converts single phase power from Locomotive Transformer to three phase 50Hz power to supply to all auxiliary loads of Electric locomotive. It is direct replacement of Single phase to three phases ARNO Converter.

SYSTEM DESCRIPTION
Single Phase to Three Phase 180KVA Static Converter will take Single Phase Supply from the Locomotive main transformer tertiary winding and will use a Rectifier to derive a stable DC link voltage and unity power factor at input stage. The DC Link is unaffected by supply voltage variations. This DC link will be used as input to the three - phase Inverter, which will utilise IGBTs to synthesise a three-phase Sine Weighted PWM waveforms, with a fundamental voltage of 415 Vrms line to line. Since IGBTs are used as switching devices in the inverter, the system reacts fast to any of the fault conditions and protects itself and loads from all fault conditions. A Battery Charger is also built-in to cater to DC loads and to Charge the battery.
