Cycloverter

Usado em Locomotivas e EMU

​

Used on EMU where the supply originates from 15 kV or 25 kV ac single phase.The Cycloverter is an active front end inverter that accepts a single phase supply from the train transformer with variations of +25%/-30%.

The power factor applied to the supply is unity.The Cycloverter converts the single phase to 700 Vdc which then powers 3-phase inverters for brake compressors, air conditioners and other 3-phase requirements. Multiple inverters fitted to adjacent cars can be phase-lock-looped to form one 3-phase grid throughout the train.Inverter power range is from 6 kW to 30 kW per inverter.

 

Used on EMU and locomotives where the supply originates from 3-phase auxiliary alternators. Inverter offer unity power factor to the supply.Inverter power range up to 150 kW.
