Single phase line commutated AC-DC converter

  1. Feb 9, 2004 #1
    Been stuck on a problem for a while...any help would be much appreciated.

    A 100V dc motor is supplied from a converter whose ac input is supplied by a 1.5kVA transformer with 8% leakage impedance. The nominal supply input to the transformer is 120 V at 60 Hz. For purposes of design I'm to assume that it can vary between 110 V to 126 V. I need to determine the transformers turns ratio and the commutation time and rate of current change ratings at max DC current draw by the motor at nominal ac voltage of 120V.

    Any advice that would lead me in the right direction would be great.

    Thanks in advance
