*holds a 9v battery up to the screen and zooms out until the size matches*



Whoa, quite a brick there. Is that a module? or a single IGBT with 3 connections to split the current up?

It's 3 seperate IGBT's in the same package, all paralleled for some ridiculous ratings...

Apparently it can handle 2500 V at 1200 amps.

NO IDEA WHAT TO DO WITH IT.

where did you even get it?
are they used in electric train motor inverters?
you can definately make a induction furnace if you have a mega watt power line running to your house

Ooh, that's a beautiful brick smile
I'd suggest an OLTC, but you only have 1, and OLTCs tend to eat bricks. No point in starting a project hinging around a part you only have 1 of when said part is likely to be driven to destruction; you'll feel rather sad when the project dies because the brick died frown
If you had, say, 7 more you could make a scary DRSSTC (4 for the bridge, 4 to replace it when you break it in the quest for more power wink )
Or you could sell it.
Out of curiosity, what are the switching speeds like?

The switching speed is around 1-3 uS if i remember right.... sort of slow, but its a big brick.
