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.

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 !
