I need to convert 115 vac 60 hz to 115 vac 400 hz 1 and 3 phase, 12 -
15 amps and 26 vac 400 hz single phase at a couple of amps. I want to
simplify the mess I spread around on my bench when I need 400 hz. I'd
like a single unit that gives me what I want. Is there a fairly simple
way to do this?

I'd look around for a surplus 400 Hz generator set that doesn't run.
Odds are you can find one, and the price will be next to give-away as
400 Hz is not useful for any backup power needs. Then replace the
generator's gas/diesel engine with an electric motor that (with the
right pulleys) will spin the generator head at the right RPMs.

You can probably do it for under 200 dollars. Check SteelSoldiers and
Smokstack for leads on generators.


Good advice! Most people try to do this sort of thing the hard way...
hung up on "solid state" ;-)
