I'm looking to rectify 240 VAC into DC with 100 amp surge capacity.
This will power the servo amps on my Matsuura bedmill. I probably
won't ask as many questions as Iggy about my winter projectVBG

The largest I found is 50 amp:http://www.digikey.com/scripts/DkSea...l&name=641-138...

Do I need to come up with some way to put three in parallel? If I do
this do I need to fuse each rectifier?

If a 100 amp unit is out there, my life would be simpler.

Digikey lists rectifiers up to 400A

The anode/cathode studs let you use only two heatsinks.

If Digikey doesn't bring you joy, try Newark -- they seem to list more
'heavy industry' sort of electronics than Digikey.

You may also want to check Surplus Sales of Nebraska:
http://www.surplussales.com. They have a lot of heavy metal electronics
surplus, and I've never gone wrong buying from them.

Do you need to implement control loops in software?
"Applied Control Theory for Embedded Systems" was written for you.
