Re: [TCML] IGBT 1200V, 54A

Terry -
   
  As far as use in a SISG tank circuit, what IGBT parameter do you feel is the limiting factor: voltage, or pulse current?
   
  Aside from damage from a primary strike, has anyone reported IBGT failure during "normal" operation?

  Possibly, but after Phil's testing the extra thermal mass may not be 
needed. The OLD IGBT was the largest available because we did not know 
any better. A much smaller IGBT may do perfectly fine.

I still lurk here and make comments when time permits ;-)
