__ Concept__:

For a fully controlled three phase bridge rectifier,

\({I_{rms}} = \sqrt {\frac{2}{3}} \times {I_0}\)

__ Calculation__:

Given that, output load current (I_{0}) = 100 A

In a fully controlled three-phase bridge converter,

RMS value of the A.C. line current

\({I_{rms}} = \sqrt {\frac{2}{3}} \times {I_0} = \sqrt {\frac{2}{3}} \times 100 = 81.64\;A\)A
