If the diode has cut in voltage Vr = 0, the output waveform of the circuit is

A.

B.

C.

D.

Please scroll down to see the correct answer and solution guide.

Right Answer is: D

SOLUTION

For the given input waveform, we obtain the output voltage waveform considering the positive and negative half cycles.

CASE I :

For positive half wave of the input, the diode D1 and D3 will be forward biased and diode D2, D4 will be reverse diode. So, equivalent circuit diagram is

Applying KVL in Loop 1,

…..(1)

CASE II:

For negative half cycle of the input, the diode D4 and D2 will be ON, and D1 and D3 will be OFF. So, the equivalent circuit is

Applying KVL in Loop 2,

Thus, from the obtained results in above two cases, we get the complete output waveform as
