I have a strong suspicion that the cap to which you are referring is placed on the primary side as a "power factor" correction measure. I have noticed that many new power supplies are beginning to include power factor correction as a feature.Originally posted by Screamtruth@Apr 20 2006, 06:37 PM
I have been repairing a lot of power supplies lately and I have noticed that there are a few that have capacitors on the input side of the step down transformer. Any ideas why this is? Stability, transient protection?
