Fig. 4.7(a) presents the power circuit of the single-phase full-bridge rectifier, and
Fig. 4.7(d) shows the rectifier waveforms when the load current is pure dc of

value. For the single-phase full-bridge rectifier the equations of the single-phase full-wave rectifier with center-taped transformer hold except Eqs. (
4.67) and (
4.70–
4.76). The diodes D
1 and D
4 during the first half-cycle are forward biased and during the second half-cycle the diodes D
2 and D
3. Therefore, the pair of diodes D
1 and D
4 is conducting during the first half-cycle and the pair D
2 and D
3 during the second half-cycle.
