Power ElectronicsFreewheeling Operation

One important benefit of a freewheeling diode in an inductive rectifier load is reduction of?

  • ANegative load-voltage excursions
  • BAverage load current to zero
  • CLoad inductance
  • DSupply frequency
Report an error
Correct Answer: A. Negative load-voltage excursions
Explanation: The diode provides a local current path and clamps the load voltage near zero during freewheeling, preventing substantial negative load voltage.
Reference: Standard power electronics: freewheeling operation
