Hi, a power supply @ 25vac, 50Hz in and a variable 0-20vdc, 10a out. A ripple smoothing capacitor will be added parallel from + to after the full wave rectifier. I found the formula. C = (5 X Io) / (Vs X F)
C = farads
Io = output amperes
Vs = voltage between the capacitor & rectifier.
F = Hz
I want looking for a 10% ripple.
Is this formula ok? Do you double the Hz? How does the 5 represent the 10% ripple? And would you work out the entire math, so I can study it?
Thanks
