Ever in search of the most extravagant way to do something (followed

I know of, the PowerTec, but they come big....

Baldor has some nice ones up to 3HP, but probably not cheap.

You know you need a special drive for them, right (not a regular SCR
drive intended for DC motors). The commutation is done externally and
electronically.

Wow, Bodine has a 115ac drive that puts out 320vdc.

Sure, 2 caps and a bridge rectifier and you've got ~300VDC, just like
in a pee-cee supply.
