Capacitor Filter Operation

S Bharadwaj Reddy
Capacitor filter.  Fig. shows a typical capacitor filter circuit.  It consists of a capacitor C placed across the rectifier output in parallel with load RL. The pulsating direct voltage of the

What is a Filter Circuit ?

S Bharadwaj Reddy
Generally, a rectifier is required to produce pure d.c. supply for using at various places in the electronic circuits. However, the output of a rectifier has pulsating character i.e. it

Capacitor Filter Working Principle

S Bharadwaj Reddy
A half-wave rectifier with a capacitor-input filter is shown in Below Figure. The filter is simply a capacitor connected from the rectifier output to ground. RL represents the equivalent resistance of
