IGBT SSTC finally possible?

Hello all,

Forgive me if this topic has already been discussed, but I haven't read any 
posts from the list for over a year.

Just been looking at the international rectifier homepage, and in 
particular the  IRG4PF50WD, a new "warp" speed IGBT that can be used in 
hard switching applications up to 100kHz.

Was thinking it would be nice to make a multi kW, ~600v input, SSTC with 
some of these. Any reason why this isn't possible (turn-off time still too 
long?) I was thinking it would be interesting to use some of these to drive 
my 12" secondary which resonates well below 100kHz.

What changes would need to be made to a regular mosfet SSTC circuit?
