It is planned to use the transformer shown in Fig. 1, a 12-pulse rectifier. Each secondary is connected to three phase controlled bridge rectifier. The two rectifiers are connected in series to supply a highly inductive load. 1. Based on the phasor relationship between different windings. If suitable turns ratio is selected, is it possible to use this transformer to produce 12 pulse output voltage? Show the reason behind your answer. 2. Assuming this arrangement is possible to be used in 12-pulse rectifier, draw the output voltage of the 1st and 2nd rectifier and give the relation of the total output voltage. 3.
