Find the average value of output voltage of a basic step-down chopper, with duty cycle = α and load = R Ω.

(a) I = Vs x α

(b) I = (Vs x α)/R

(c) I = 0

(d) I = Vs/R

I had been asked this question during an internship interview.

I'm obligated to ask this question of Choppers-3 in section Choppers of Power Electronics

Right answer is (b) I = (Vs x α)/R

Best explanation: Vo = Vs x α

I = Vo/R.
