A single-phase thyristor controlled bridge rectifier is supplying a dc load of 1 kW. A 1.5 kVA isolation transformer with a source side voltage rating of 120 V at 50 Hz is used. It has total leakage reactance of 8% based on its rating. The source voltage of nominally 115 V is in the range of ±10%. Assuming load current is nearly constant, find: (i) The minimum turns ratio of the transformer, if the dc load voltage is to be regulated at constant value of 100 V, (ii) The reduction in average load voltage due to commutation, and (iii) The value of firing angle a when the source voltage is 115 + 10% Y
