The output voltage across the secondary transformer is 100Vrms.

To get the average output voltage of the diode we need to use this formula(Vm=2*Vrms/)-->Vm=2*100 = 200V.

The voltage across the diode is 200V, assuming it is an ideal diode. So the PIV should also be equal to 200V. The answer should option A.

@Jason Garcram.

It's given that 100v is the peak value. Then how this answer option B? Explain please.

In half-wave rectifier, PIV voltage is the maximum peak voltage.

So, the Correct option is C.

Vrms = 0.707(Vp).
Vrms = 100V,
100 = 0.707 (Vp),
Vp = 141.4 V Answer is (B).
(2)

Should it not be 100V?

As PIV of half wave rectifier is Vm.

Sankar said:   8 years ago
Yes, C is the answer.
