Question 1
Power ElectronicsFreewheeling Diode

A freewheeling diode connected across an inductive DC load mainly provides?

  • AA path for load current when the main switch or rectifier device stops supplying it
  • BA permanent short circuit across the source
  • CGate current for an SCR
  • DVoltage amplification
Report an error
Correct Answer: A. A path for load current when the main switch or rectifier device stops supplying it
Explanation: Inductive current cannot change instantaneously, so the freewheeling diode provides a path for continuing current and helps limit load voltage excursions.
Reference: Standard power electronics: freewheeling diode
