  • Question

  • A single phase half wave rectifier is feeding a resistive load. When a = 0, dc output voltage is 127 V. When a = 30°, the dc output voltage will be about


  • Options
  • A. 127 V
  • B. 120 V
  • C. 110 V
  • D. 100 V

  • Correct Answer
  • 120 V 

    Explanation
    Using Eq A single phase half wave rectifier is feeding a resistive load. When a = 0, dc output voltage is 127

    A single phase half wave rectifier is feeding a resistive load. When a = 0, dc output voltage is 127 = 0.933.

    Hence Vdc for 30° firing angle = 0.933 x 127 = ? 120 V.
