Question

Which of the following statements are true about the given circuit?

(a) The circuit is that of a bridge rectifier

(b) The PIV of the diode D1 must be greater than v0 for the circuit to function as a bridge rectifier

(c) For silicon diodes, the value of v0=(vi-1.4) V

(d) All of the mentioned

The question was asked in an international level competition.

I want to ask this question from Diode Gates and Rectifiers in portion Diode Circuit of Analog Circuits

Answer 1

The correct choice is (d) All of the mentioned

To explain: The circuit is that of a bridge rectifier. For proper functioning, the PIV of diodes must be at least greater than v0 and since, the current through any path flows through 2 diodes. There is a drop of 1.4 V.
