Beschreibung
Zusammenfassung:	A method is provided for operating a rotating field machine of a motor vehicle, wherein at least two winding systems of the rotating field machine are supplied with current from an intermediate circuit via a transmission device having at least two switching units and wherein respective switching sequences for the switching units for supplying the winding system in question are defined. For the switching sequences, first switching states in which current is drawn from the intermediate circuit and second switching states in which no current is drawn are defined. The first switching states of the respective switching sequences are defined so as to be free of overlap. For at least one of the switching sequences, third switching states are defined, in which current is fed into the intermediate circuit. The third switching states are defined so as to overlap with the first switching states of the other switching sequence.
