Since FW Rectifiers have output frequency than HW Rectifiers the time between peaks for the FW Rectifiers would be shorter since f=1/T and the time between peaks for the HW Rectifiers would be longer which would explain why HW Rectifiers have more ripple.

Ripple means how much AC present in DC output.

Ripple factor is measured as effectiveness for an rectifier circuit.

Ripple factor is frequency dependent.

Friends,

If we use capacitive filter if the peaks comes quickly or to soon then capacitor will not get full time to discharge so we will get better dc output.

If we use inductive filter then quick transition of low and high value of the rectifier output the inductor will oppose the change.

(as inductor opposes any quick change in current across it) so we will get the smoother output.

For better understanding please refer to the capacitive and inductive filter for full-wave rectifier.

No man, Ripple factor of a half wave rectifier is 1.21& full wave is 0.48.

In my views, ripple factor is the compensate occur in the output waveform. And due to less ripple factor in full wave. Then half wave full wave has shorter time between their peaks.

Ripple factor for
half wave rectifier=0.48
full wave rectifier=1.21

Half wave peak have alternate peaks where as full wave have have cosecutive peaks.

Can you show the diagram and explain.
