    Sintered IGBT modules you say? (What the hell am I going to do with this thing?)

    I found something the other day when went looking for some of my fishing gear. I have a good amount of fishing gear, and it gets separated into manageable bundles and stored wherever it'll fit. In any case, when I was looking through some stuff, I found a piece of gear which I totally forgot I had.
    A few years back, I acquired a bunch of electronic parts from a guy who needed to clear out his garage bays so he could tear it down. I used and kept some of it and gave away/recycled most of it (this was where I got that old dual beam Tek scope). Anyway, one of the things I got was what looked like some sort of huge power module. I had no idea what it was or interest in it back then, but if I wanted anything, I had to take everything. I knew a lot less about electronics at the time and didn't even bother to look it up.
    When I found it, I took a picture and joking mentioned that it my new power supply for a ultrasonic transducer project. But what it actually is, is a massive inverter used in solar/wind applications. It's an older model, but it must have cost.... i don't know, $1000 at the time? I've been reading about it and it's a pretty impressive piece of gear. Check it out:

    The amount of power this can handle is RIDICULOUS
    here's a datasheet:
    SKIIP642GH120.PDF

    So, my question(s): What should I do with this thing? Can I sell this thing at this point?
    I know I can always use an aluminum block like that one. Will I ever need eight 2000F/500V polypropylene capacitors for a project?

    Experience is something you get, just after you really needed it.

    Both, great ideas.

    (Forgive me, I know I'm a little lare to the partywith on this)
    When I started reading about these (IGBTs), the first thing I thought was "ooh! Class D amp!"
    These things have a bit of transconductance, don't they? I checked out the curves, and looked over at the Y axsis and was like, "f-cking Amps??!"

    sale into audiophile site in Europe and ask for two grands- those guys are crazy for this kind of stuff, just to have enough patience to find the right buyer and a little lobby , of course

    Apparently, people do sell these on ebay and surplus sites. One site had a comparable unit for A-$1599. But all the ones I've seen don't include the caps. Maybe I remove those and keep 'em
