5.3. IGBTs (Insulated-Gate Bipolar Transistors)

Try these first

1. 1.

   What does IGBT stand for?

   Hint

   Think of the components: insulated, gate, bipolar.

2. 2.

   Name one application of IGBTs.

   Hint

   Think about energy and motors.

3. 3.

   What does the IGBT mainly combine functionalities from?

   • MOSFETs and BJTs
   • Only BJTs
   • Only MOSFETs

   Hint

   Recall its full form and applications.

4. 4.

   True or False: IGBTs can only conduct current in one direction.

   • True
   • False

   Hint

   Think about the characteristics of the device.

5. 5.

   Analyze a scenario where an IGBT fails to turn on in a circuit designed for motor drives. What could be the possible reasons?

   Hint

   Think about the connections and temperature effects.

6. 6.

   Consider the implications of using MOSFETs in place of IGBTs in a high-voltage application. What issues may arise?

   Hint

   Assess the differences in object handling capabilities.
