Jim Yes I think volume is the $$$ driver. Another idea is get a Cummins/Onan 12kW RV house power generator. RV market unit might be more aggressively priced and would have higher temp ratings then a residential unit. 240V 50A. Best Regards DS
Typically, though, those would be single phase - Maybe my idea of 3 phase power for easy rectification is not as useful as I might have thought. Although, the thought of somehow synchronizing 3 single phase generators is an intriguing project in itself - I would assume that like any generator, if you hook it to a stiff bus, it will tend to synchronize, so maybe the idea of a small threee phase motor would work. Of course, it might also be horribly unstable, and it's not like the information needed to design it would be published (or even measured).
Hmm, three small cheap harbor freight generators, a cheap used 3 phase motor, and a (potentially destructive to the generators) experiment is born.
Filter capacitors might actually be easier. Anyway I do it, I'm looking at large mass.
