Development of i. g. b. t. based 3-phase 415vac, 25kva inverter for railways ac coaches railways ac coaches Lead acid storage battery inverter for railways ac coaches

This is the design and development of IGBT based Booster_inverter Technology.

It works on the principle of “Chopper and Inverter” technique.

It evolves the chopping of the input voltage by using IGBT’s at high frequency to generate a high DC link voltage. This DC link voltage is applied to the Inverter input. The inverter Converts this DC Link voltage into 3-phase AC Supply.
