should I ground the rectifier terminal ?
« on: August 09, 2010, 05:40:35 AM »
I want to get 5v dc from main supply(220v,50Hz), I'm using the circuit attached here, problem is bridge rectifier has four terminals(two for input and output) in which I'm suppose to use  one output terminal and give the same to regulator, what about the other terminal of the rectifier?
 can I ground that, if so will I get 5v dc ?

If the circuit is wrong then please post a valid circuit :)

Look at a schematic for the internals of the bridge rectifier. Then trace out the current flow during each half-cycle of the Mains AC input.
That should help you understand what is needed for connections.
