| In a three phase (50Hz) full converter, the ripple frequency in output voltage?
A. 50 Hz
B. 100 Hz
C. 150 Hz
D. 300 Hz

Right Answer is: D
SOLUTION
Concept:
Ripple frequency at the output = m × supply frequency
fo = m × fs
Where m = types of the pulse converter
Calculation:
A three-phase full-wave AC to DC converter is a 6-pulse converter
Number of pulses (m) = 6
fo = 6 × supply voltage frequency
∴ f0 = 6 x 50
f0 = 300 Hz
