A three phase fully controlled bridge converter is connected to a 440 V supply, having a reactance of 0.3 Ω/phase and resistance of 0.05 ohms/phase. The converter is working in the inversion mode at a firing advance angle of 35°. Calculate the average generator voltage. Assume average load current to e is 60 A and thyristor drop of 2 volts.
