medium · MCQ · Q-B317E9
If the input frequency of a full-wave rectifier is , the output ripple frequency will be:
- A.25 Hz
- B.50 Hz
- C.100 HzCorrect answer
- D.200 Hz
Solution
In a full-wave rectifier, both the positive and negative half cycles of the input AC are rectified into output DC pulses. Thus, for each cycle of input AC, there are two pulses of output DC, making the ripple frequency double the input frequency ().
