Basic DC Theory
Another type of full-wave rectifier circuit is the full-wave bridge rectifier. This circuit utilizes
four diodes. These diodes actions during each half cycle of the applied AC input voltage are
shown in Figure 8. The output of this circuit then becomes a pulsating DC, with all of the waves
of the input AC being transferred. The output looks identical to that obtained from a full-wave
rectifier (Figure 7).
