ABSTRACT:
An improved method and apparatus for operating a converter fed rotating field machine to obtain better utilization of the converter rectifiers in which the stator windings of the machine are fed with non-sinusoidal phase currents with one phase current always limited to a maximum value and the other phase currents increased by the difference between that maximum value and a typical sinusoidal wave current. This is accomplished in such a manner that the power and torque of the rotating field machine are not affected.
