A single phase half-wave AC voltage controller provides output RMS voltage of 50V when the triggering angle (a) is 90°. For the same a, what is the output RMS voltage if the AC voltage controller changed to full-wave type.

A three-phase half wave control rectifier is operated from 3-phase source 230 V, 50 HZ (supply) with load resistance R = 10 22. An average output voltage of 50% of the maximum possible output voltage is required. Determine a) firing angle, b) average and rms value of load current, and c) the efficiency.

Q4 / three phase half wave controlled rectifier is used to feed a resistor load of ( 10 ohm) the source is (208 volt) star connected: calculate: 1- The average value of the voltage and current on the terminal load if angle (45). 2- The average of the voltage on the terminal load if angle (80). 3- The angle required to get 7 amp. 4- Draw the circuit.

If the frequency of the input signal applied to a full wave rectifier is 120 Hz, then what will be the frequency of the output signal?
