Due to non sinusoidal waveform of the input current, the power factor of the rectifier is____________?
Correct answer: D. Both (a) and (b)
- A. Negatively affected by firing angle
- B. Negatively affected by distortion of the input current
- C. Positively affected by both firing angle and distortion of the input current
- D. Both (a) and (b)
Explanation
Rectifier power factor is the product of displacement factor and distortion factor. The firing angle increases the displacement, while the nonsinusoidal input current causes distortion, so both effects reduce power factor.
