What is the best way to figure the capacitor voltage? I have two cases: the output from the rectifier (half wave or full wave, sqrt(2)*RMS). I have typically used the peak voltage, multiplied it by 1.5, and chosen the first stock voltage rating that exceeds this value. Is there a better way? Is my choice of 1.5 reasonable? The second case is for the output from the regulator, I use the same formula. However, I suspect that since I have a regulator, perhaps 1.5 is too large a factor. Suggestions?
