On which of the following factors the number of phases for which a rectifier should be designed depend ?
Correct answer: E. all of the above
- A. The voltage regulation of the rec¬tifier should be low
- B. In the output circuit there should be no harmonics
- C. The power factor of the system should be high
- D. The rectifier supply transformer should be utilized to the best ad-vantage
- E. all of the above
Explanation
The number of phases is selected by considering ripple and harmonics, voltage regulation, power factor, and effective use of the supply transformer. Since all listed factors matter, the combined choice is applicable.
