In a controlled rectifier, delaying the firing angle generally provides control over the?

  • AAverage output voltage
  • BSupply frequency
  • CNumber of semiconductor layers
  • DPhysical transformer turns ratio
Report an error
Correct Answer: A. Average output voltage
Explanation: Phase control changes the portion and polarity-weighted interval of the AC waveform applied to the load, thereby controlling average output voltage.
