In a 3 phase half wave rectifier, when firing angle is less than 90 degree, then the average dc output voltage becomes__________________?
Correct answer: A. Positive
- A. Positive
- B. Negative
- C. Zero
- D. None of these
Explanation
For a three-phase half-wave controlled rectifier, the average output remains positive when the firing angle is below 90 degrees. A negative average is associated with operation beyond the rectification range.
