Ok, I'm looking for a way to go from DC to 3 phase AC, in both small and large applications. For now, just to satisfy my curiosity, I'd like to make some small 3 phase AC motors on a small scale, so I was thinking my DC input would be a bank of AAs or Ds, either 4, 6, or 8, so 6, 9, or 12v. So, very small scale.
I'd also like one that could be used to say, drive about a 100HP motor.
I haven't found much, I found this site
Correct me if I'm mistaken, the timer is putting out a square wave and the point of the large capacitor and filter are to make this more sinusoidal?
Do you think this diagram would be good for my small scale application, because that last capacitor is looking pretty mighty.
Finally, I bought a 2200uF cap instead of 2700, which I think would be fine, but I just noticed it says 50WVDC, is this a max capacity or would it be very bad to use it with 9V of DC?
Oh, I also couldn't find a 1uH filter, only a 100uH, I realize that's two factors off, but how precise do I need? I'm less familiar with filters (first I've heard of a microHenrie).
