Hi Everyone, I believe I posted about work I have been doing on power supply regenerated noise from the power line or a human induced ESD event. At the very least I believe this effect can explain some system, manufacturing, and field problems. It may also be a safety problem as power supplies after a year in use may no longer pass safety standards.
I published a paper at the Institute of Physics in England a while ago before I realized the importance of the finding. I am going to present my new data that I am currently generating next Friday at 10 am PDT. If you are interested contact me (info below). So far I have seen the heretofore not described effect on every supply I have tested, in four different locations using different equipment and on a total of ten power supplies. I will complete building a pulse generator to test supplies quickly and apply a long term test fir safety issues (500,000 pulses over a week's time. By next Friday I will have tons of additional information. Three more power supplies are arriving today of widely different designs. By Friday I hope to dissect one of the supplies to identify the mechanism whereby a 1400 pulse can breakdown a 6 kV barrier. I am pretty sure I know what it is but need to confirm. You do not want a supply that does this in your system and most seem to do it.
