1. What will be the average DC output voltage if 300 V input AC voltage (line-to-line rms) is given to a 3-phase controlled full-bridge rectifier operating with firing angle of 30 degree?
2. Is it possible to get zero average output voltage while applying 200 V AC input voltage. If yes, under what condition it can be obtained?
3. What is the power factor for a three-phase controlled full bridge rectifier at a firing angle of 60 degrees?
4. What will be the effect on source current waveform, on using resistive load instead of highly inductive load.
5. How many thristors conduct under each mode of operation of a 3-phase controlled bridge rectifier?
