Can I use an old microwave transformer as a ballast?
I am going to rectify my household current/voltage (110V with a 30 Amp breaker) into DC and then use a high powered mosfet to switch at a high frequency for some experimenting.
I am sure the breaker will jump so I am wondering if a used microwave transformer with its high voltage output shorted and its low voltage side put in series with the mains voltage will act as a ballast. It still has the magnetic shunts in place and I will put it motor oil for insulation.
Is this correct? If not what should I do?
I forgot to say that the way I plan it is:
The mains first, the MOT in series second (ballast/inductor) and THEN a full bridge recifier with a smoothing capacitor.
No DC is going into the MOT, just one of the wires going from side to side of the low voltage side of the MOT.
Is this still dangerous? What if I put a 30uF 120V AC capacitor before the MOT for power factor correction? Any better?
If you short out the one side, aren't you just making an inductor? Anyhow, here is where I go for these sorts of questions- good people- http://www.electro-tech-online.com/
