1. An arrangement for optimizing a transport time delay associated with a thyristor power supply which is effective for supplying power to a motor, said optimizing arrangement comprising:

  • said thyristor power supply including a plurality of thyristors which are fired in a sequentially controlled manner so as to produce such power to said motor;

    means for calculating a gate firing angle for a next one of said plurality of thyristors, said calculating means performing such calculation at a first predetermined time following gating of a previous one of said plurality of thyristors;

    means for recalculating said gate firing angle at a second predetermined time just prior to gating of said next one of said plurality of thyristors; and

    means for preventing such calculated gate firing angle of said calculating means from overriding such recalculated gate firing angle produced by said recalculating means.
