Re: Large IGBT need help

Stealing my terms again I see Matt ;-)  Anyway I suggest you start small and
use some IGBTs like the 50N6S2D Don't try to use those large ones.  There is
no reason to.  At 20v, they have  26nF gate capacitance.  Steve Ward can
only drive them safely with the UCC37322/1's because he is running them
