A three phase to single phase cyclo-converter employs a 6 pulsebridge circuite. This device is fed from 400 V.,50Hz.supply througha star/delta transformer whose per phase turns ratio is 3:1 .For an output frequency of 2Hz., the load reactance isw0L =3 Ω., The load reactance is 4 Ω. Thecommutation overlape and thyrister turn - off time limitthe firing angle in the inverter mode to 1650. Compute(a) peak value of r.m.s. output voltage (b) r.m.s.output current(c) output power.
