Still not sure what you are doing or how you intend to use it. I can tell you that the rise time of the current through this or any other inductor is not impressive, they do the opposite of what I think you want, they don't block DC, and the blocking time for an AC waveform is probably going to be a lot shorter than what it takes to charge a cap bank.
On a more helpful note, if you have been blowing IGBT's, try a big MOSFET instead. More expensive, like $20 vs $7, but much better at withstanding punishment.
