The PIV rating of each diode in a bridge rectifier is ___________that of the equivalent center-tap rectifier?
Correct answer: A. one-half
- A. one-half
- B. the same as
- C. twice
- D. four times
Explanation
For the same transformer secondary peak voltage, each bridge diode withstands only the secondary peak voltage, whereas each centre-tap diode withstands twice that voltage. Therefore, the bridge rectifier diode PIV is one-half of the equivalent centre-tap value.
