Ripple frequency of three-phase full-wave converter:
Figure: output voltage waveform of three-phase full-wave rectifier.
From the above output voltage waveform, we can observe that for a complete one cycle of input supply we got 6 pulses in the output.
So, the three-phase full-wave ac to dc converter is a 6-pulse converter.
Then the ripple frequency of the output f0 = m × f
Where,
m = number of pulses in the output per one complete cycle of the input
f = supply voltage frequency
Solution:
For single-phase full-wave bridge circuit f0 = 2 × f
For a three-phase full-wave converter f0 = 6 × f
Hence, the ratio output ripple-frequency to the supply-voltage frequency = f0 / f = 6
