Venue: Calcutta Institute Of Technology (Uluberia, West Bengal)
1. Aptitude Test (Technical)
3. PI (Technical mostly)
Mainly conceptual questions from power electronics. The chapters covered are:
Opam, SCR, power amplifier, MOSFET, CRO, BJT, transmission Line, Boolean algebra etc.
Some of the questions that I could remember are:
1. Fly back time is associated with ___ (CRO)
2. I/P impedence of Opam is ____ (high)
3. ohmic contact helps to drive ____ (MOSFET)
4. The SWR is associated with ____ (transmission line)
Total candidates appeared: 118
Our topic was PRESENT INFLATION.
Q: Why do you want to join?
Q: Will you accept transfer?
Q: Could you draw the Two transistor analogy of SCR?
Q: How is Opam used as comparator?
Q: Why is MOSFET preferred than BJT in power systems?
Q: Diff between Class A & class B amplifier.
Q: Why is Push pull arrangement used?
Q: What will happen if the load of an Half wave rectifier is replaced by capacitor. Draw The wave form.
All you have to do is to boost up electronics to the fullest that is enough.
The interviewer was very witty and encouraging so don’t get tensed give your 100% n you are through. The result was declared around 12 am and thank God I was one of the selected ones! Best of Luck!
