Wow I just thought I'd check the thread. This was very eventful!!! That bathtub tank is the coolest thing I have ever seen!

I just checked the datasheet:
http://www.pwrx.com/pwrx/docs/cm600dy_12nf.pdf

So, a JUNCTION (inside the IGBT) temperature of 150degC max. The IGBTs are 0.11degC/Watt from junction to case. So, 100watt burning up inside one of the IGBTs (high or low side) means the junction is 11 degrees hotter than the case. So, we could figure out the junction temperature if we know the base plate temp and the amount of heat being generated inside. But there are 2 IGBTs per package, so I guess 200w would mean 11degC hotter, since each IGBT could be burning 100w.
