Power ElectronicsFreewheeling Operation

When an ideal freewheeling diode conducts across an RL load, the load voltage is approximately?

  • AZero
  • BEqual to the negative supply peak
  • CTwice the supply peak
  • DInfinite
Report an error
Correct Answer: A. Zero
Explanation: The conducting ideal diode effectively shorts the load terminals for the freewheeling interval, making load voltage approximately zero while current circulates.
Reference: Standard power electronics: freewheeling operation
