The ripple factor indicates the number of ripples present in the DC output.
The output of the power supply is given by:
Mathematically, ripple factor (r) is defined as:
\(r= \frac{{{I_{rms}}\;of\;AC\;component}}{{{I_{DC}}\;component}}\)
Thus if the ripple factor is less, the power supply has fewer AC components and the power supply output is pure (i.e more DC without much fluctuations)
Thus ripple factor is an indication of the purity of output of the power supply
Important Points:
For the Half-wave rectifier, the ripple factor is = 1.21
For a Full-wave rectifier, the ripple factor is = 0.48
For the Bridge-wave rectifier, the ripple factor is = 0.48
From the above points, we can say the ripple factor of a full-wave rectifier is less than half the ripple factor of a half-wave rectifier.
