METHOD FOR CONTROLLING A MULTI-PHASE ELECTRIC MACHINE BY MEANS OF SPACE VECTOR MODULATION, CONTROL DEVICE, AND DRIVE ARRANGEMENT

The invention relates to a method for controlling a multi-phase electric machine (2), wherein: a stator (3) of the electric machine (2) comprises a first sub-system (4a) and a second sub-system (4b) having the same number of phases (Ph1a, Ph2a, Ph3a, Ph1b, Ph2b, Ph3b) and separate star points (S1, S2); an inverter device (9) is controlled by means of space vector modulation in order to generate output voltages for each of the phases (Ph1a, Ph2a, Ph3a, Ph1b, Ph2b, Ph3b); the output voltages are output as pulse sequences (UPh1a, UPh1b); and each of the pulse sequences (UPh1a, UPh1b) in the second sub-system (4b) are output inverted with respect to the pulse sequences (UPh1a, UPh1b) in the first sub-system (4a). 本发明涉及一种用于操控多相电机(2)的方法，电机(2)的定子(3)具有第一子系统(4a)和第二子系统(4b)，第一子系统和第二子系统具有相同数量的相(Ph1a、Ph2a、Ph3a、Ph1b、Ph2b、Ph3b)并且具有分开的星形接点(S1、S2)，为了产生用于相应的相(Ph1a、Ph2a、Ph3a、Ph1b、Ph2b、Ph3b)的输出电压，借助空间矢量调制操控逆变器装置(9)，将输出电压作为相应的脉冲序列(UPh1a、UPh1b)输出，并且在第二子系统(4b)中的相应的脉冲序列(UPh1a、UPh1b)相对于在第一子系统(4a)中的脉冲序列(UPh1a、UPh1b)倒转地输出。
