    Calculation of AC line current in a three-phase bridge converter

    Given:
    - AC supply voltage = 415 V, 50 Hz
    - Output current = 100 A
    - Output voltage = 400 V

    To find:
    - RMS value of the AC line current

    Assumptions:
    - Large inductive smoothing
    - Neglect overlap

    Formula:
    - Iline,rms = Iout/sqrt(3)

    Calculation:
    - Output power = P = Vout x Iout = 400 x 100 = 40,000 W
    - Input power = P = Vline x Iline x sqrt(3)
    - Input current = Iline = P/(Vline x sqrt(3)) = 40,000/(415 x sqrt(3)) = 81.65 A (rounded off to two decimal places)

    Therefore, the RMS value of the AC line current is 81.65 A.
