Mason,
A co-worker just tossed some 75Amp, 1400V half bridges
last week. I'll dig through the recycle bin and see if I can
find them. If not I can probaby get some other modules
laying around. What voltage module are you looking for?
Regardless there is lots of goodies that my company will
never use that I can send, even some extras so you can
toast a few.
Give me the address off list and I'll send them your way.

I'm building a battery load tester for a school design project and I'm
looking for an IGBT or MOSFET to modulate the load. I was curious if
anyone had one sitting around (maybe from a blown controller?) that
you wouldn't mind getting rid of. I'm aiming for a maximum continuous
current of 50 amps, so something with a rating higher than that would
be great. The bigger the better... then I don't have to worry (as
much) about heatsinking and venting. ;)
For those that are interested, this is going to be a pretty nice
device! My team is using LabVIEW to monitor and control our unit. It
will work with a "typical" automatic battery charger and allow the
user to select the desired discharge rate and load test cutoff
voltage. Our device will then activate the external charger, recognize
when the charger is done, deactivate the charger and perform the load
test, then re-activate the charger and report the results of the load
test. A nice, automated device for testing EV batteries... and not too
bad of a senior design project either!
Anyway, if anyone has an available transistor that meets the criteria,
name your price and feel free to email me offlist. Thanks!
