A single phase full bridge converter supplies power to constant current load. If the triggering angle is 45°, what is the input power factor of the converter?
- A. 0.637
- B. 0.837
- C. 0.937
- D. None of the above
Answer: A. 0.637
Explanation: Input power factor of 1-phase full converter = (2√2/π) cos α = (2√2/π) cos 45° = 2/π ≈ 0.637.
