Hmmm, I'am afraid I do not understand it really.
Energy stored in capacitor is: E = 0.5 * C * U^2 ,right?
So if I use zener to limit the maximum voltage across cap, it is automatically limited stored Q=C*U and Energy adequately, right?
All I need is to assure infallible connections between cap...
I need to design intrinsically safe portable apparatus for use in zone 0 in hazardous locations. It's first project of that kind, I have a fundamental question. I have rad thru IEC 60079-0 and 60079-11 normative documents. There is information, that electrolytic caps cannot be used as blocking...
