This post is in continuation of post below: (starting a separate thread as suggested)
https://www.electronicspoint.com/threads/combining-two-ac-sources-rectifier.273712/
1. I have two ac sources, 220V ac 50 Hz(from mains & generator) & have to run a circuit from it for which I need dc supply.
There is SMPS in the circuit which I didn't shown. It makes 12Vdc.
2. I had connected a bridge rectifier to each source. After that each output is shorted.
3. There may be three cases: Only main available, only generator available, or both are available.
4. I think problem may arrive when both ac sources are available.
Also it could be one may be at different angle then other. Like if first ac source have crest, other couls have trough or at some phase from each other.
5. I have tested the circuit by connecting two 220V ac source from plug. basically its a short i.e phase1 of ckt is connected to phase 2 & similarly neutral.
However in this circuit both phase & amplitude is same.
But in real circuit, there will be different phase generator & main voltage. I don't know how this circuit will behave then.
