Bridge rectifier and subsequent components

[notallbad]

Please forgive the silly questioning.

I know theres half and full but which is this? Or is it more depending on how its placed in a cct?
D3SBA20

So although theres not actually any AC on the output of the rectifier (or at least shouldn't be) would you expect to get a reading from a DMM on the AC range due to the pulsing DC?

I think it's fullwave rectifier, the part number you mentioned. You only need one diode for half-wave rectification.

You should get an ac reading because of the ripple voltage.

Thankyou both.
I shall read through that and try to expand on it to try and understand it all a bit better.
OK, so ripple on the rectifier output, this would then be smoothed by a cap or 2.

My question now is, ok theres ripple on the rectifier, but would the output of a Linear volt reg (connected on the rectifier outputs) also have ripple on it? There are 2 which provide + and - 12v.

Re: Bridge rectifier and subsequent components

As the instructive documents point out, the part is a "rectifier bridge" - 4 diodes hooked up to rectify the AC on a 2 wire secondary. Bridges differ from full wave (2-diode) in that the full wave design requires a center tapped secondary to provide the return.
