Hi Friends,
Somehow, i do not understand this word completely. I came across "Desaturation" in IGBT because of a circuit which was a 3Phase AC motor driver.
There's a block which senses that the IGBT is coming close to Desaturation and prevents it through a slow stop signal at it's Gate (Base).
They say that when this Desaturation occurs, there is an increase in the collector potential : Does that mean the transistor go into Active region? Please help me understand guys. Here is a schematic which I am referring to :
Thanks,
Pawan
