Question

Calculate the output voltage of the Boost converter if the supply voltage is 1 V and duty cycle value is .9.

(a) 10 V

(b) 20 V

(c) 40 V

(d) 60 V

I got this question during an interview.

Question is from Solid-State Devices in chapter Introduction to Solid-State Devices of Electric Drives

Answer 1

The correct option is (a) 10 V

The explanation: The output voltage of the buck converter is Vo = Vin×(D). The value of the duty cycle is less than one which makes the Vo < Vin . Vo = Vin×(1-D)=10 V.
