Question

If peak voltage on a center tapped full wave rectifier circuit is 5V and diode cut-in voltage is 0.7, then peak inverse voltage on diode will be ___________

(a) 4.3 V

(b) 10 V

(c) 5.7 V

(d) 9.3 V

I have been asked this question in my homework.

I'd like to ask this question from Fullwave Rectifier topic in portion Diode Circuit of Analog Circuits

Answer 1

The correct option is (b) 10 V

For explanation: PIV is the maximum reveres bias voltage that can be appeared across a diode in the circuit. If PIV rating of the diode is less than this value breakdown of diode may occur. For a center tapped full wave rectifier, PIV of diode is 2Vm. Therefore, PIV is 10 V.
