Gunter,
I discuss this on pages 71-72 of my book, Electronic System Design: Interference
and Noise Control Techniques, published by Prentice-Hall in 1987 (now out of
print, but you might find a copy by searching for the ISBN number
0-13-252123-7). A 50-250nF capacitor across each rectifier usually works
well.

Subject: RE: Conducted emission testing for EN55022 - diode + caps
Hello
"Take care to bridge the rectifier diodes
with capacitors, otherwize thay might create interference themselves."
Does anybody have some material (papers, book references, etc) about using
capacitors in parallel with the rectifier diodes (with use them, how to
determine their capacitance, etc ) ?
Thank you !
