A step-down delta-star transformer, with per-phase turns ratio of 5 is fed from a 3-phase 1100 V, 50 Hz source.
The secondary of this transformer is connected through a 3-pulse type rectifier, which is feeding feeding an R load.
Find the average value of output voltage.
A. 220 V
B. 257 V
C. 1100/√3 V
D. 206 V
