EEE UNIT 3 E VEHICLE 2 MARKS

 

Here are 5 two-mark questions from Unit III – Electronics and Sensor-less Control in EV, designed using Apply, Analyze, Evaluate, and Create levels of Bloom's Taxonomy, along with model answers:


1. Apply Level

Q: Apply your understanding of power semiconductor devices to recommend whether an IGBT or a MOSFET is more suitable for high-voltage inverter applications in EVs. Justify your answer.
Answer:
IGBT is more suitable for high-voltage applications because it can handle higher voltage and current with lower conduction losses compared to MOSFETs, making it ideal for inverter circuits in EVs.


2. Analyze Level

Q: Analyze the safety challenges involved in handling high-voltage components in electric vehicles.
Answer:
High-voltage EV systems can cause severe electric shock, fire hazards, and component damage. Proper insulation, automatic disconnection systems, and protective equipment are essential to ensure user and technician safety.


3. Evaluate Level

Q: Evaluate the effectiveness of sensor-less control techniques in autonomous electric vehicles compared to traditional sensor-based methods.
Answer:
Sensor-less control reduces system cost and improves reliability by eliminating physical sensors. However, it may have limitations under low-speed conditions or rapid dynamic changes where sensor feedback could be more accurate.


4. Analyze Level

Q: Analyze how the phase inductance-based method contributes to rotor position estimation in sensor-less motor control.
Answer:
In the phase inductance-based method, the inductance varies with rotor position. By measuring this variation, the system can estimate rotor location without physical sensors, enabling sensor-less motor operation.


5. Create Level

Q: Create a simple model to demonstrate how observer-based control can be implemented for estimating speed in a BLDC motor.
Answer:
An observer-based model uses real-time voltage and current inputs along with motor parameters to estimate rotor speed and position. Kalman Filter or Luenberger Observer can be implemented in the controller software to simulate this.
