Question

For a single phase half wave rectifier, with R load, the diode is reversed biased from ωt =

(a) 0 to π, 2π to 2π/3

(b) π to 2π, 2π/3 to 3π

(c) π to 2π, 2π to 2π/3

(d) 0 to π, π to 2π

The question was posed to me by my college director while I was bunking the class.

The doubt is from 1P-Diode Rectifiers HW-1 topic in division Diode Rectifiers of Power Electronics

Answer 1

Correct option is (b) π to 2π, 2π/3 to 3π

To explain I would say: Diode will be reversed biased in the negative half cycles.
