    Just as an exercise I am trying to program a microcontroller to take a rectified single phase AC current and through PWM convert it back to single phase AC current. I keep reading that this is typically only done when starting with 3 phase AC current. Is it not possible to do this with single phase AC current?

    Yes, you can do it with single phase too.

    Making sure you isolate the AC from the mains and be careful running the code! I would probably use a low-power transformer and a resistance in series so that you don't burn anything out. Just attach a small load to see how you are doing..

    I was thinking of initially trying it out with a small 12 - 24 volt ac motor just to make sure I have the concept correct. Eventually I would like to use it to control a 120V water pump on a fish tank.
