A method and arrangement for optimizing the filtration of conducted highfrequency disturbances in a frequency converter, the frequency converter being coupled with a feeder to a supply network and having a variable switching frequency. The method comprises steps of defining a common mode disturbance current of a frequency converter feeder, comparing the magnitude of the defined common mode disturbance current with a predetermined limit value, and changing a switching frequency of the frequency converter, when the common mode disturbance current exceeds the predetermined limit value. <IMAGE> |
