In a voltage-source inverter, shoot-through of one bridge leg means?

  • AThe upper and lower switches of the same leg conduct simultaneously
  • BAll switches remain OFF
  • COnly the load current becomes zero
  • DThe DC source is disconnected safely
Report an error
Correct Answer: A. The upper and lower switches of the same leg conduct simultaneously
Explanation: Simultaneous conduction of both devices in one leg creates a very low-impedance path across the DC link and can damage the switches.
