  • Question

  • A single phase half wave rectifier is feeding a resistive load. Input voltage v = Vm sin ?t. The output dc voltage is Vdc and output rms voltage is Vrms . If firing angle is 180°, Vdc and Vrms respectively are


  • Options
  • A. 0 and 0
  • B. A single phase half wave rectifier is feeding a resistive load. Input voltage v = Vm sin ?t. The out
  • C. 0 and - Vm
  • D. A single phase half wave rectifier is feeding a resistive load. Input voltage v = Vm sin ?t. The out

  • Correct Answer
  • 0 and 0 

    Explanation
    Put a = 180° in Eqs A single phase half wave rectifier is feeding a resistive load. Input voltage v = Vm sin ?t. The out

    Otherwise also a = 180° means no conduction.

    Hence zero output voltage.
