In simple words, smoothing can be defined as the circuit which is done to eliminate the ripple from the yield of a direct current power supply.
Explanation:
Necessity of smoothing:
Smoothing can be also applied in the form of a capacitor that acts to decrease or level out variations in a signal. And these capacitors are mostly used after power supply in voltage.
The yield DC voltage of a half-wave rectifier provided in the figure of a sinusoidal wave.
In a method to provide a constant DC voltage from a corrected AC source, a filter or smoothing circuit is required.
