I understand that Simon, but that way you get half the capacitance of one capacitor on it's own but you double the voltage rating (with resistors across pos/neg on each capacitor).simon wrote: ↑Sun Jan 30, 2022 10:16 pm Sounds like a bipolar PS - +0-. If so the two caps joining - to + will be ground or 0V most likely, the point in the middle. Think of the two caps stacked vertically - from top to bottom the top cap will be + above -, the bottom cap will be + at the top - at the bottom. The negative of the top cap is joined to the + of the bottom cap.
Dennis is trying to increase capacitance, so as long as the capacitor voltage rating is above the rail voltage (by a fair margin) surely capacitors in parallel is what's needed ? (ie all pos connected together and all neg connected together)
10,000uf + 10,000uf (@50v) in series = 5,000uf @ 100v
10,000uf + 10,000uf (@ 50v) in parallel = 20,000uf @ 50v
