Method for controlling a pulse width modulated converter, control device for a pulse width modulated converter, converter arrangement and electric drive system

摘要

The present invention relates to adapting a PWM frequency in a power converter as a function of the input voltage of the power converter. By adjusting the PWM frequency in the converter depending on the input voltage, a ripple on the input side of the converter can be varied. In particular, it is possible at high input voltages to minimize by adjusting the PWM frequency, the ripple and thus reduce the sum of input voltage and ripple.
