Dave,
Any tips, design details, or weblinks that you may have found useful when
building your saturable ballasts?

Chris,
If you had the budget, I'd put one of these in each leg of your three
phase power circuit. You would need three units, but I've had good luck
running my TCs with saturable reactor ballasts. They are infinitely
adjustable with the rectified output of a small Variac.
Perhaps they would give you a price break on three of them.
