Frequenzumrichter mit bedämpftem Gleichspannungszwischenkreis

摘要

The invention relates to a frequency converter (1) having a current-compensated inductor (18) which is situated in a direct voltage intermediate circuit (5) and which comprises a magnetic core (19) made of a nanocrystalline material. The inductor (18) serves to dampen asymmetric interferences generated by an inverter (6) and to prevent these from being introduced into a network (3).
