Question 1
Power ElectronicsSwitching Losses

Switching loss in a practical semiconductor device occurs mainly during?

  • ATurn-on and turn-off transitions
  • BThe ideal OFF state only
  • CThe ideal ON state with zero voltage drop
  • DMechanical rotation
Report an error
Correct Answer: A. Turn-on and turn-off transitions
Explanation: During switching transitions, appreciable voltage and current coexist for finite time, producing energy loss.
Reference: Standard power electronics: switching losses
