Abstract: The invention relates to an adjustment of a PWM frequency in a power converter in accordance with the input voltage of the power converter. By means of the adjustment of the PWM frequency in the power converter in accordance with the input voltage, a ripple on the input side of the power converter can be varied. In particular, it is possible, in the case of high input voltages, to minimize the ripple by adjusting the PWM frequency and thus to reduce the sum of the input voltage and the ripple.

Abstract: 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.
