Consider the diode to be an ideal one and Vo = Vr + Vdc during positive half cycle. Thus, during the negative half cycle

(a) Vo = Vr

(b) Vo = 0

(c) Vo = Vdc+Vr

(d) Vo = Vdc

I have been asked this question in a job interview.

My doubt is from Diode Circuits-3 topic in section Diode Circuits of Power Electronics

Right answer is (d) Vo = Vdc

The explanation is: During the negative half diode is not conducting hence Vr (voltage across the resistor) = 0. Vo = Vdc.
