Interview Questionnaire
5 Questions
- Q1. What are the motors used for Electrical Vehicles ?
- Q2. Why in case of DC machine , Field pole arrangement is on stator and Armature Winding on Rotor ? what happens if reverse ?
- Q3. Why stability is improved using decreasing reactance in power flow equations ?
- Q4. Why IGBT is Voltage source and BJT is current source device ?
- Q5. In IGBT , Voltage across Gate to source will controlled the performance of IGBT i.e More charge carriers will available as Gate Source voltage increased. Hence Voltage controlled device.
- Ans.
IGBT is a voltage-controlled device where the performance is influenced by the voltage across the gate and source.
IGBT stands for Insulated Gate Bipolar Transistor.
The voltage across the gate and source controls the conductivity of the IGBT.
Increasing the gate-source voltage allows more charge carriers to be available, enhancing the device's performance.
IGBTs are commonly used in power electronics applications due to t
