Question 1

The power electronic converter shown in the figure has a single-pole double-throw switch. The pole P of the switch is connected alternately to throw A and B. The converter shown in figure is _____?

Question 2

A DC chopper is built employing an electronic switch as shown below. Determine the power absorbed by the switch. Assume switch to be ideal.

Question 3

A Boost converter operates with D = 1, then output voltage will be __________?

Question 4

In step down converter, output voltage V0 is held constant at 5V by varying the duty cycle α. If dc input voltage varies from 10-40 V, output power P0 ≥ 5W and frequency of switching is 50 kHz then minimum value of ‘L’ required to keep the converter operation in a continuous condensation mode is_____?

Question 5

A Buck converter is designed to produce an output voltage of 5 V from a 9 V dc source. It is connected across a load resistor of 75 Ω. Determine the value of inductance that will ensure continuous current for the switching frequency of 450 kHz.
