IGBT's in Place of MOSFET's

Hi,

Today after blowing fets in my H bridge due to a bad tuning pot on a TL494, 
Steve Ward suggested that I could use some IGBT's instead of the fets.  I 
have a good supply of IGBTs and they are beefier then the mosfets I was 
using.  My question is, how can I be sure that four of these IGBT's isnt 
going to overload my gate drive IC's?  I have 30N6S2 IGBT's and my current 
H bridge is full of 44N50's.  Does anyone have any advice?
