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.

The Ripple factor for full-wave rectifier is given by: r= Iac/Idc = 0.482

Zero

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

Ripple factor can be defined as "the ratio of the root mean square (rms) value of the ripple voltage to the absolute value of the dc component of the output voltage." This is usually expressed as a percentage.

The ripple factor of Half wave rectifier is the ratio of the rms value of the ac components to the dc value of the component

The higher the load current the higher the ripple voltage across the filter capacitors. It is directly proportional.

In a DC power supply, a low-pass RC filter is typically used to "filter the voltage" by reducing or eliminating any remaining ripple. This works because such ripple has frequency components over 0 Hz (ripple is essentially an AC component with an offset), which are suppressed by the low-pass filter.

Ripple factor can be defined as the variation of the amplitude of DC (Direct current) due to improper filtering of AC power supply.it can be measured byRF = vrms / vdc

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.

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 ...

Either less ripple voltage with the same filter capacitance, or similar ripple voltage with smaller filter capacitances (and thus physically smaller filter capacitors).

it is the distortion or noise present in the signal or harmonics
