A method for actuating a frequency converter (520) comprises steps for measuring phase currents (831, 832, 833) which flow in phase conductors (531, 532, 533) of a three-phase supply system (530), for generating a first modulation space vector (572) which has an angle (573) which is synchronous to a system voltage of the three-phrase supply system (530) and has a fixed modulation index (575) as amplitude, for generating a third modulation space vector (873) as a function of the first modulation space vector (572) and the measured phase currents (831, 832, 833), and for modulating the frequency converter (520) in accordance with the third modulation space vector (873). |
