Hi,
Can we apply Mains (AC supply) to bridge rectifier? (If yes, can anyone suggest specific bridge rectifier for mains AC?
What should I consider when selecting bridge rectifier?
Thank you,
hi,
Yes you can apply mains directly to a suitable bridge rectifier.
You should consider the local mains rating voltage and the required current.
I guess you know there will be no isolation from the mains supply on the output.

Thank you ericgibbs!!!!!!
I would like to try something today the lab, what could be the result when I apply Mains (AC) to the bridge rectifier and then DC to the same bridge rectifier. (I know for the DC, I will get some less voltage at output than input voltage because of the voltage drop of diodes.) But still wanted to try it out.
For isolation, I can use transformer after bridge rectifier when I applied AC mains. Is it correct?
My load (which is the what I am looking for as an output) 24Vdc with 2Amp current.
No, the transformers goes BEFORE the bridge, DC doesn't go through a transformer.
In which case you don't need a mains voltage rectifier, just a lower voltage (and higher current) one.
Hi Nigel,
I am looking to apply AC or DC to Bridge Rectifier first. Yes, DC can not go through the transformer and that is why my original post is about bridge rectifier (which is capable of both AC and DC.). I did not get your second point.
You're wanting 24V DC, so you have a mains transformer that converts the incoming mains down 24V (or less), so the rectifier only works at 24V, not mains.
Perhaps you better explain EXACTLY what you're trying to do, because you don't seem to understand what you're mentioning here.
