Abstract
A device includes an EMC (electromagnetic compatibility) filter, a frequency converter coupled to the EMC filter, and a motor coupled to the frequency converter via a motor cable. A leakage current compensator includes a leakage current detector and a compensation current generator configured to generate a compensation current that is directed against the leakage current and is overlaid on the leakage current in such a way that the leakage current is reduced.
