I applied via Company Website and was interviewed in Apr 2024. There were 2 interview rounds.

Round 1 - GATE TEST 

(1 Question)

  • Q1. You have to get a good score on the GATE exam to get the chance for an IIT Interview. I scored a rank of 850 in the general category and got PhD electrical interview call from IIT Madras
Round 2 - One-on-one 

(10 Questions)

  • Q1. Please tell me something about yourself.
  • Q2. Why do you have applied for the direct PhD after your Btech.
  • Q3. What is your favourite topic Power Electronics or Machines?
  • Ans. 

    Power Electronics

    • I enjoy working with power electronic circuits and devices

    • I find the control and conversion of electrical power fascinating

    • Power electronics plays a crucial role in renewable energy systems

    • Examples: inverters, converters, motor drives

  • Answered by AI
  • Q4. Please draw the current flowing through the RL circuit (I vs t). What will be the value of current at t=0.
  • Ans. 

    The current flowing through an RL circuit is initially zero and increases exponentially over time.

    • At t=0, the current in an RL circuit is zero as the inductor initially resists changes in current

    • As time progresses, the current in the RL circuit increases exponentially towards its maximum value

    • The time constant of the RL circuit determines how quickly the current reaches its maximum value

  • Answered by AI
  • Q5. What if we add one capacitor c also in the series (RLC series) and draw the I vs t graph?
  • Ans. 

    Adding a capacitor in series with RLC circuit will affect the current vs time graph.

    • The addition of a capacitor will introduce a phase shift in the current waveform.

    • The presence of the capacitor will cause the current to oscillate at a different frequency compared to the original RLC circuit.

    • The amplitude of the current waveform may also change with the addition of the capacitor.

  • Answered by AI
  • Q6. We want to make 100 v dc to 40 v dc and draw the buck converter for this purpose.
  • Ans. 

    To convert 100 V DC to 40 V DC, a buck converter can be used.

    • Buck converter steps down voltage by controlling the duty cycle of a switch

    • It consists of an inductor, a diode, a capacitor, and a switch (usually a MOSFET)

    • Example: Use a buck converter with a duty cycle of 0.4 to convert 100 V DC to 40 V DC

  • Answered by AI
  • Q7. What will be the voltage across the diode in the buck converter.
  • Ans. 

    The voltage across the diode in a buck converter depends on the input voltage, duty cycle, and load resistance.

    • The voltage across the diode is typically equal to the input voltage minus the voltage drop across the diode.

    • The duty cycle of the buck converter affects the average voltage across the diode.

    • The load resistance also impacts the voltage across the diode.

    • For example, if the input voltage is 12V, the diode has a ...

  • Answered by AI
  • Q8. What will be the voltage across the capacitor? Why it is so? You are drawing based on memory tell me some logic behind this. What will be the ripple in this and the amplitude of this curve?
  • Ans. 

    The voltage across a capacitor depends on the charge stored on it and the capacitance. Ripple and amplitude of the curve depend on the input waveform.

    • Voltage across a capacitor is given by V = Q/C, where Q is the charge stored on the capacitor and C is the capacitance.

    • The ripple in the voltage across the capacitor depends on the input waveform and the load on the capacitor.

    • The amplitude of the curve will depend on the ...

  • Answered by AI
  • Q9. What will be the final voltage?
  • Ans. 

    The final voltage will depend on the specific circuit and components involved.

    • Final voltage can be calculated using Ohm's Law (V = IR) where V is voltage, I is current, and R is resistance.

    • The final voltage may also be affected by factors such as the type of power source, circuit configuration, and any voltage drops across components.

    • It is important to consider the voltage rating of components to ensure they can handle...

  • Answered by AI
  • Q10. Which books have you studied in your Btech to learn these concepts?
