    Abstract: PROBLEM TO BE SOLVED: To provide a method for operating a rotary electric machine, in which the rotary electric machine is connected to a converter circuit with a DC voltage circuit for connecting at least two voltage levels, and the phases of the converter circuit are connected to the DC voltage circuit in accordance with a selected combination of switching states for power semiconductor switches in the converter circuit. SOLUTION: When a torque track or a stator magnetic flux track is out of a range of a predetermined values in a switching state combination of the torque track and the stator magnetic flux track, in order for operation of the rotary electric machine to be possible over a sampling time L, maximum values are determined from a torque violation value and a stator magnetic flux violation value, and those maximum values are added. The switching state combination is set up as a selected switching state combination, in which the sum of maximum values is the minimum value. Alternatively, the sum of the torque violation value and the stator magnetic flux violation value is obtained over the sampling time L, to use it as a maximum value of the sum. The switching state combination is set up as a selected switching state combination, in which the maximum value is the minimum value. COPYRIGHT: (C)2009,JPO&INPIT
