In Reply to: RE: Slight change in power supply cap value - problem ?? posted by Caucasian Blackplate on June 16, 2015 at 09:29:06
Hello,
I put together a drawing of what I tried to describe above. I was thinking that one pair of caps has the 440 in between, and the other a resistor divider leg (perhaps not best description), so not strictly in series. Is this what you were concerned about? If so, suggestions on alternatives would be appreciated.

Do this instead.
Hello,
If the dual capacitors are structured as you say, with a common -, then this is impossible. In your diagram the lower 1/2 220 has the - tied to ground, and the upper portion would require the - tied to 440.

I might suggest that you are way, way over your head on this project.
The upper capacitor is one can capacitor with the two halves paralleled.
The bottom capacitor is one can capacitor with the two halves paralleled.
You ground the ground of the bottom can capacitor.
You connect the positive side of the bottom capacitor to the negative side of the upper capacitor.
Hello,
That is what is depicted in my schematic, if you look closely. Each upper capacitor (2x100uf) is independent and the - is connected to the + of the capacitor below it. Fortunately the - terminals of both lower capacitors are connected to ground, allowing the use of a common ground dual capacitor.
In your schematic, the two capacitor segments on the right side share a ground ( - terminal) - they are the 2 halves of the 2 x 220uf capacitor. It is not possible to connect the + of one side of that capacitor to the - of the other half, because there is only one - for both capacitor sides and you already have it connected to ground. Maybe the terminology of 1/2 of 2x220 was not clear.....
Regards -- Roger
Ah, I thought the two capacitor symbols wrapped in a shroud represented two capacitors inside one can.
In any case, you have two 2x100uF caps, use each one like a 200uF/500V cap, and stack them for the first stage. For the second stage, purchase another pair of identical capacitors.
