Full-Wave Rectifier Circuit:
A full-wave rectifier circuit is a circuit which rectifies the whole cycle of the AC sine-wave. The basic full-wave rectifier uses two diodes. An action of these diodes in during every half cycle is displays in Figure.

Another category of full-wave rectifier circuit is the full-wave bridge rectifier. This circuit utilizes four types of diodes. Those diodes' actions during every half cycle of the applied AC input voltage are display in Figure. The output of this circuit then becomes a pulsating DC, along with all of the waves of the input AC being transferred. The output seems identical to which obtained from a full-wave rectifier.
