This is a question about the output caps on either a switcher or a linear power supply...
Say I want to connect two supplies in series, to increase voltage. Do those output
caps need to be of a higher voltage rating, or not?
I've tested this on the bench, and no smoke, but at least not immediately...
(don't try this without isolating the ground plane on switchers.)
What I have in mind is to series several laptop supplies... or, maybe I want
to series my LM317, or my newer LM723 supplies. Both of those are limited
to 40v, but I want more! (about 90v, for driving 1/4hp pump motors or other
"work" related projects, plus other nefarious experiments just for the hell of it.)
And yes, I work with isolation transformers when working with mains.
