Thanks for the ideas waross, keep them coming. I should probably have provided more details in my original post. There are potentially a lot of ways to skin this cat. For prototyping, we using a lab grade Pacific Power AC source that works well, but costs and arm and a leg, and weighs more...
As for light dimmers, we're looking into things like that (especially "sinewave" dimmers, rather than just the standard phase-angle fired triac approach), but we're also looking for a 3-phase 480V input to help slot into existing infrastructure. Do you have a manufacturer that you like for 10kW...
I'm working for a company that is making Stirling engine cryocoolers. We have a single phase, permanent magnet linear motor that reciprocates at 60Hz. You vary the amount of cooling by modulating the voltage applied the the windings. More voltage equals more linear motion, which displaces a...
