25kVA Static Inverter

The 25kVA Static Inverter was designed and manufactured for underslung mounting on railway coaches.

The Inverter uses IGBT technology to convert a nominal 110V DC supply into a 415V AC, 3 phase, 50Hz power supply for air-conditioning units and associated loads, such as coach fans and lights, fans, compressors etc., that are installed in conventional coaches in international markets.

The inverter operates by boosting the input DC voltage to establish an intermediate 600V DC link voltage & modulating this link voltage with a three-phase IGBT bridge to produce a pulse width modulated three-phase voltage. The Inverter output is internally filtered to produce a pure sinusoidal output waveform.
