Sorry for the elementary question... I've used Quasimodo to determine the snubber when I only have two secondary leads when I'm using a bridge rectifier, no problem.
Now how do I hook up my scope and bell ringer if the secondary has a center tap for a full wave rectifier? Do I need to snub each half independently? Or do I just measure for a snubber that will span peak to peak? And have a snubber that ignores the center tap. Wouldn't it be better to snub both separately since the diodes fire alternately? Also if one is testing each half winding separately do I put the ringer and scope across the center tap and one of the outer leads? I'll short all other windings. Do I need to short the other outer secondary lead to anything, or let it float?
