Diodes and Applications

Q1:

The peak inverse voltage (PIV) across a nonconducting diode in a bridge rectifier equals approximately:

A half the peak secondary voltage

B twice the peak secondary voltage

C the peak value of the secondary voltage

D four times the peak value of the secondary voltage

ANS:C - the peak value of the secondary voltage

Ans C is right ,
# piv for half- wave rectifier is Vm
# full-wave rectifier is 2Vm
# bridge rectifier is Vm
Because which are the entire secondary voltage appears across the non-conducting diodes
As far question option C is correct.
