Hello I know that this may be a dumb question but I have found conflicting info about this on a few web pages. If one takes say 5 capacitors each with a value of 500wv @ 150uf and connects them in series the result wold be 2500v @ 30uf. Correct? Under ideal conditions (perfect capacitors with no leakage resistance, etc.) the effective capacitance would be 30 uf and the voltage capability would be 2500 volts. If the original capacitors were pre charged to 500 volts, the series connected capacitors would produce 2500 volts. As a practical matter 5 capacitors connected in series would require ballast resistors to equalize the leakage current, and some voltage derating to allow for incomplete equalization. Now if one takes another string just like the one above, and connects both strings across the output of the rectifier parallel to each other does this still give the 2500v but @ 60uf? or does the voltage drop? Capacitors in parallel retain their voltage rating, and their capacitances add. Thanks Gordon -- John Popelish |
