Hello again. Full of questions this morning that I have been trying to figure out for some time.
Equalizing resistors to share voltage evenly between stacked, rather in-series, filter capacitors.
At a maximum, the resistor's value should be 50 / capacitor value. So for a pair of 220uF caps in series would have a maximum of 2x 470kΩ resistors, one attached to each capacitor in parallel.
My first question is to ask if this is correct? Would the calculation be 50/.00011 or 50/.00022? I calculated for 50/.00011 = 454,545Ω
So if a maximum of 470kΩ resistors can be used, that would suggest that it could also be less than 470kΩ. How low can you go? And more importantly what are the pros vs cons in doing so?? I have read about the speed in which the capacitors are topped off, but is there a benefit to doing this faster or slower?
Thank you!!!!
