Maybe I could just use an ungodly small capacitor for the calculation...?? :confused:

The final intent of this exercise is to be able to measure the ripple to determine the health of the diode bridge. The supply is variable 0 - 300 VDC.

So what is/are the formula/s with the smoothing capacitor?

I'll never get there. No matter where I go, I'm always here.
