when is ripple fator minimum
Ripple factor ripple factor is very important in deciding the efficiency of the rectifier .ripple factor give the total power converted AC input to the DC output. Ideal ripple factor should be zero and power factor 1. Ripple factor of half wave rectifier 1.21 and full wave rectifier is 0.48.

You reduce ripple voltage by adding a low-pass filter. In the simplest case, you put a capacitor after the rectifier. The peak voltage will be the rectifier output voltage less the forward bias of the rectifier, while the minimum voltage will depend on current and capacitance. In a more complex case, you could use an LC filter, making the peak voltage smaller. Specifics are dependent on the power and performance requirements.
it is nothing but ac ripple neutralizer
Ripple factor ripple factor is very important in deciding the efficiency of the rectifier .ripple factor give the total power converted AC input to the DC output. Ideal ripple factor should be zero and power factor 1. Ripple factor of half wave rectifier 1.21 and full wave rectifier is 0.48.
ripple factor:=21/2 /3 *Xc/XL
The Ripple factor for full-wave rectifier is given by: r= Iac/Idc = 0.482
Ripple factor and form factor both are inerrelated to each other since they represent the extent to which filtering is done(ripple) and rms value of ac is greater than the average value(form). ripple factor=Vr(p-p)/V(dc) form factor=V(rms)/V(av)--Jivan Nepali
when a.c convert in d.c then some components of a.c remain with it called ripple factor
Zero
Ripple factor (γ) may be defined as the ratio of the root mean square (rms) valueof the ripple voltage to the absolute value of the dc component of the output ...
Ripple, in DC power supplies, is technically unitless. Ripple voltage is specified in Volts/Volt, or a percentage. For example, a 12VDC power supply with 120mV (pk-pk) of ripple voltage is (0.12/12) = 1% ripple voltage.

Ripples will increase if capacitance is decreased.
