Power Electronics Internship Test

Intern has to take Power Electronics internship test in which they will be asked 50 multiple-choice questions. They have to score grade A or A* on this test to be eligible for the internship. Here’s a sample set of questions on the Power Electronics topic.

1. Which of the following is true in case of a forward biased p-n junction diode?
(A) The positive terminal of the battery sucks electrons from the p-region
(B) The positive terminal of the battery injects electrons into the p-region
(C) The negative terminal of the battery sucks electrons from the p-region
(D) None of the above mentioned statements are true
View Answer

Answer: A
Explanation: The diode is forward biased, positive is connected to p & vice-versa, as such batter provides EMF to drive electrons from n-region to p-region.

2. A power diode with small softness factor (S-factor) has
(A) small oscillatory over voltages
(B) large oscillatory over voltages
(C) large peak reverse current
(D) small peak reverse current
View Answer

Answer: B
Explanation: Peak reverse current is independent of S-factor smaller the value of S-factor larger the oscillatory over voltage.

3. In case of a practical p-n junction diode, the rise in the junction temperature ___________
(A) decreases the width of the depletion region
(B) increases the barrier potential
(C) increases the width of the depletion region
(D) width of the depletion region increases but the barrier potential remains constant
View Answer

Answer: A
Explanation: The rise in temperature excites the charges, which go & recombine with the charges in the depletion region decreasing its width. Higher the temperature, lesser is the E.M.F required to turn on the device.

4. A Schottky diode can be switchd off much faster than an equivalent p-n junction diode due to its
(A) higher operating frequency
(B) no recombination of charges
(C) more compact structure
(D) None of the mentioned
View Answer

Answer: B
Explanation: Due to the metal-silicon junction there are no stored charges, hence no reverse recovery time due to which the switching is faster.

5. Zener diodes allow a current to flow in the reverse direction, when the
(A) voltage reaches above a certain value
(B) temperature reaches above a certain value
(C) current always flows in the reverse direction only
(D) current cannot flow in the reverse direction
View Answer

Answer: A
Explanation: Zener diode has voltage regulating property. When voltage reaches above a certain value (Zener voltage), current starts to flow in the reverse direction.
