Fig. 4.1(a) shows one of the simplest single-phase full-wave diode rectifiers. During the first half-cycle the input voltage has positive values forcing diode D
1 to be forward biased and diode D
2 reverse biased, and thus D
1 is conducting, connecting the power supply to the load terminals. The equivalent circuit of the rectifier during this mode of operation is shown in
Fig. 4.1(b). During the second half-cycle, the input voltage has negative values forcing diode D
2 to be forward biased and diode D
1 reverse biased and thus D
2 is conducting, connecting the input voltage across the load. The equivalent circuit of the rectifier during this mode is shown in
Fig. 4.1(c). As can ...
