Base Plate, with area milled flat where the IGBTs will go:

3 600v 600amp IGBTs:

copper, nomex, copper sammich. hmm hmm good: haha

With enclosure. Enclosure is around 4.3" tall. The 3 capacitors aren't here yet, so I can't mount that:

And it's cheap too! Here's where I got it. That works out to like $4 per controller for the isolation material:
kits and boards
