- Re: equalizing resistors across series capacitors.
-
- I'll use rough values. You have two 500 uF capacitors in series, with
- about 500V across them, total. That's at least 250V across one of them.
- A 100-ohm resistor here would burn an incredible 625 watts.
-
- I would try paralleling about 500k across each capacitor, and then
- testing the voltage in service to see if the capacitors have approximately
- equal voltages across them. If not, then lower the resistor values,
- keeping in mind that V**2/R is the power running through the resitors.
- You may need to use high wattage resistors.
