Title: Transformer output
Post by: dan stanton on February 19, 2010, 04:46:17 PM

Hi all. I'm trying to find the formula for the rectified output of the secondary. Haven't been in electronics for 35 years. So, a 12V secondary gives me 15V? Power supply. Thanks in advance.
P.S. I am reading Teemuk's book.

Vrectified = 1.4 x Vsecondary

Hi, if you wish to refresh your memory this covers most of them.
I found this extremely helpful some years back.

If the jpeg does not load,, go here first, http://evatco.com.au/hamptchoke.htm (http://evatco.com.au/hamptchoke.htm)

click on,, Transformer Selection Guide

There are some hidden gotch-ya's with rectification, wise to note the "I" (current) as well as voltage obtainable from AC secondaries. 8|
