what to do with 2 high power devices I have aquired
« on: July 19, 2021, 06:22:15 pm »
both are toshiba, one is a 75l6p43 3 phase bridge rectifier. the other seems to be a igbt device. I know what I want to do with the rectifier, no clue what to do with the other.

if I dont figure out what to do with the igbt, maybe I can send it to noopy so he can crack it open and take pictures.

How about a solid state tesla coil (SSTC)

Pretty ordinary, 600V 100A half bridge, mediocre speed (pretty fast for its day I suppose):
https://pdf.searchdatasheet.com/datasheets-0/toshiba/MG100J2YS40.pdf

You're unlikely to use it at continuous capability (~10kW) without industrial power supply and application, but it would do fine in an offline power converter of a few kW (just running at reduced ratings, no sweat), or pulsed at a few 10s kW (like an SSTC).

The downside to an SSTC is, because the switching speed is relatively low, the resonant frequency needs to be low, meaning the secondary needs thousands of turns of relatively fine wire.  You'd probably want to set up a winding jig to make one, or buy one already made from eBay or whatever.

well it was in a battey backup system with tons of gel cells in it. at least 24 batterys, 12v 10ah I do belive. there were more of the half bridge things in there. but couldnt get at them easily. including 2 huge transformers.

How about a DIY induction heater of some sort?
Cryptocurrency has taught me to love math and at the same time be baffled by it.

Cryptocurrency lesson 0: Altcoins and Bitcoin are not the same thing.

The trouble with doing much of anything is, the semiconductors are a tiny cost of the overall build.  If you had salvaged most of the thing, it's possible it could be repurposed into something other than what it was; but without those materials, you'll have to build or buy them specifically for whatever thing you do.

well it was still at work. got some more bits, including one more power transistor, 2 different ones, a few capacitors, and what looks to be current sensors.

lets see I have
2 - mg100j2ys40   toshiba
1 - mg75j1zs40     toshiba
1 - pk55gb80        sanrex
1 - 75l6p43           toshiba
2 - nnc-10ga         Nana electronics
a big transformer/choke maybe.
4 capcacitors of differing values/voltages. have plans for the 75l6p43, no idea what to do with the rest. got a huge heatsink everything was attached to as well. :)
