Concept:A full-wave rectifier converts both polarities of the input AC waveform into a unidirectional, pulsating DC output across the load.
Formula:$$T_{\text{output pulse}} = \frac{T_{\text{input}}}{2} \implies f_{\text{out}} = 2 f_{\text{in}}$$
Solution:- During the positive half-cycle, one diode pair conducts and drives current through the load in a specific direction.
- During the negative half-cycle, the alternate diode pair conducts and directs current through the load in the identical direction.
- Thus, output current flows continuously across both half-cycles of the complete AC cycle.
Why other options are incorrect:- Option A: Output during only the positive half-cycle is characteristic of a half-wave rectifier.
- Option B: Output during only the negative half-cycle corresponds to an inverted half-wave rectifier.
- Option D: Output with periodic zero gaps is the signature of half-wave rectification.
