  • Patent number: 11283378
    Abstract: The disclosure relates to a method for determining phase currents of a rotating multiphase electrical machine fed by means of a PWM-controlled inverter. In this case, injection voltages applied in at least one stipulated PWM period are determined. An evaluation direction for a phase current vector is also determined and a division of current measurements for the individual phase currents is determined on the basis of the evaluation direction. The phase currents are then determined on the basis of the previously determined division of the current measurements.
