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 ...
although the AC signal is rectified the output which we get is the pulsating DC which is not desired because many appliances wok on plain DC voltage . The pulsating DC can be viewed as AC + DC component of the signal ripple factor of a rectified circuit is the ratio of AC component of signal to the DC component of the same rectified output signal. higher the ripple factor says that the signal is not smooth so lesser is its application. the components used to smooth these type of signals or to remove the 'ripple voltage' as called filters
Vp=2 Vdc=50 r=Vrms/Vdc Vrms=Vp/1.121 so r=0.028
A capacitor helps improve the ripple factor in power supply circuits by smoothing out the fluctuations in voltage that occur after rectification. When connected in parallel with the load, the capacitor charges during the peaks of the rectified voltage and discharges during the troughs, effectively reducing the voltage ripple. This results in a more stable DC output, which is particularly important for sensitive electronic devices. By minimizing the ripple, the capacitor enhances the overall performance and reliability of the power supply.
ripple can understand as rise in sine wave.thus ripple-less means a straight line parallel to x-axis i.e. bump-less line.capacitor is a component which store charge.it charge through a.c. and behave as battery on full charge.and we all know battery gives a d.c. i.e. ripple less graph.
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.
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
The Pascal second (Pa s), is the standard SI unit.
