For an RL load, a freewheeling diode can improve load-current continuity by conducting when?

  • AThe main rectifier path no longer supplies the inductive current
  • BThe load inductance becomes zero
  • CThe AC source is permanently disconnected
  • DThe gate pulse is at its maximum only
Report an error
Correct Answer: A. The main rectifier path no longer supplies the inductive current
Explanation: Stored magnetic energy in the load inductance maintains current through the freewheeling diode when the source-side device stops conducting.
Reference: Standard power electronics: freewheeling operation
