Question:
In a three-phase full wave AC to DC converter, the ratio of output ripple frequency to the supply voltage frequency is _______.
In a three-phase full wave AC to DC converter, the ratio of output ripple frequency to the supply voltage frequency is _______.
Show Hint
Ripple frequency = number of pulses per cycle × supply frequency → 3-phase full wave = 6 pulses

Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understand the nature of ripple frequency
For a 3-phase full-wave converter, number of pulses per cycle = 6. So: \[ f_{ripple} = 6 \times f_{supply} \] Conclusion:
Ripple frequency is 6 times the AC supply frequency → Option (3) is correct.
For a 3-phase full-wave converter, number of pulses per cycle = 6. So: \[ f_{ripple} = 6 \times f_{supply} \] Conclusion:
Ripple frequency is 6 times the AC supply frequency → Option (3) is correct.
