For a single-phase fully controlled bridge rectifier with continuous load current, the ideal average DC output voltage is?

  • A2Vm cos alpha/pi
  • BVm(1+cos alpha)/(2pi)
  • CVm cos alpha/(2pi)
  • D2Vm sin alpha/pi
Report an error
Correct Answer: A. 2Vm cos alpha/pi
Explanation: For continuous current and ideal devices, a single-phase full converter gives Vdc=(2Vm/pi)cos alpha.
Reference: Standard power electronics: full converters
