Question

Shown below is the diagram of an ideal super diode. When the input voltage Vin is negative, then the output voltage Vout = ?

(a) Vout/Vin

(b) Vin

(c) 0

(d) Vin * Rl

I got this question in examination.

Asked question is from Types of Diodes-1 topic in section Diodes of Power Electronics

Answer 1

Right choice is (c) 0

Explanation: When the input voltage is negative, there would be a negative voltage on the diode so it works like an open circuit. Hence no current flows through the load and Vout is zero.
