Question

Calculate the output voltage of the Buck converter if the supply voltage is 13 V and duty cycle value is .16.

(a) 2.08 V

(b) 2.24 V

(c) 2.58 V

(d) 2.54 V

The question was asked at a job interview.

Question is from Solid-State Switching Circuits topic in portion Introduction to Solid-State Switching Circuits of Electric Drives

Answer 1

Right answer is (a) 2.08 V

For explanation I would say: The output voltage of the buck converter is Vo = Vin×(D)=13×.16=2.08 V. The value of the duty cycle is less than one which makes the Vo < Vin. The buck converter is used to step down the voltage.
