The ripple factor indicates the amount of AC content present in the rectifier's DC output. A lower ripple factor means smoother DC.
Ripple Factor Values:
Half-Wave Rectifier: \( r = 1.21 \)
Full-Wave Rectifier (including Bridge): \( r = 0.482 \)
Calculation:
\( \frac{1.21}{0.482} \approx 2.51 \)
This proves that the ripple factor of a half-wave rectifier is more than twice that of a full-wave rectifier.
Conclusion:
Hence, the correct statement is:
Option 3: A half-wave rectifier has more than twice the ripple factor of a full-wave rectifier.
