| 摘要 |
The present invention relates to a method for actuating an electric three-phase current machine, in particular a synchronous machine (14), which is supplied with current by means of an inverter, the inverter having a plurality of circuit breakers that are provided to supply the electric machine with electricity in multiphase manner, it being possible to actuate the inverter in different actuation modes (I, II, III, IV, V), the actuation modes (I, II, III, IV, V) being formed by space vector modulation (I), overmodulation (II, III, IV) or block commutation (V), and the corresponding actuation mode (I-V) being selected according to a rotational speed (n) or an electric frequency (FEL) of the three-phase current machine and according to a power or torque requirement. |
