Abstract
The present invention relates to a method for controlling a distortion spectrum that arises for a switch-based inverter (), which modulates at least one output variable, by virtue of space vector modulation, characterized in that different switch positions () causing a modulation of the at least one output variable which approximates to a predefined reference signal (), are ascertained for each chronologically sequential switching process, a respective distortion spectrum for differences between the reference signal () and the at least one output variable that would arise from a respective realization of these different switch positions () is calculated, and the switch position () for which the associated distortion spectrum is most suitable according to predetermined properties is selected and implemented in the inverter (). Further provided are a corresponding system and a corresponding modulator.
