Abstract (en)
[origin: WO2022258256A1] The present invention relates to the control of an electrical power converter. The power converter is controlled with a predefined modulation frequency. This modulation frequency can be variably adjusted. In particular, the modulation frequency can be varied around a basic frequency in a predefined frequency range. The frequency range, in which the modulation frequency is varied, and also the pattern, with which this variation occurs, can be adjusted.
