Hello,
On the DC side of bridge rectifier which should be first capacitance or inductance?

ljcox,
Why then do all of the online Capacitance calculators factor in Capacitance, Frequency and Inductance?

That's only true when fully loaded, off load the voltage is equal to the peak, just like a capacitive filter.The only practical difference is the output of a capacitive input filter is equal to the peak input voltage from the rectifier while the voltage of an inductive input filter will be the RMS equivalent.

It's a nit, but the output of a loaded filter inductor is the Average of the AC waveform, not the RMS value.The only practical difference is the output of a capacitive input filter is equal to the peak input voltage from the rectifier while the voltage of an inductive input filter will be the RMS equivalent.
Of course, I was referring to the output of the rectifier. And the inductor does generate the average of the input voltage. This is true for any waveform including the output of the switch in a switching regulator. The average of a full-wave rectified sine-wave is .626Vp (2/Pi).Crutschow, sorry but I must disagree. The average of any symmetric AC wave is going to be zero. The RMS value is defined as the DC equivalent. That is why I stated it that way so all waveforms would be covered including non-sine wave sources like the output of an inverter.
