Q. A fully-controlled three-phase bridge converter is working from a 415 V, 50 Hz AC supply. It is supplying constant current of 100 A at 400 V to a DC load. Assume large inductive smoothing and neglect overlap. The rms value of the AC line current in amperes (round off to two decimal places) is
Solution:
Given that, output load current (I0) = 100 A
In a fully controlled three-phase bridge converter,
RMS value of the A.C. line current
