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.
