Beschreibung
Zusammenfassung:	A LCL filter (1) for a 1 or 3-phase grid comprising one magnetic core (2), at least one primary winding LINn, at least one secondary winding LOUTn, at least one winding Lfn for reducing flux ripples in the magnetic core (2) located between the primary winding LINn and the secondary winding LOUTn, wherein said windings LINn, LOUTn, Lfn are placed on the magnetic core (2), the primary winding LINn is connected to the input FINn of said LCL filter for connecting the filter to an inverter, the secondary winding LOUTn is connected to the output FOUTn of said LCL filter (1) for connecting the filter to a load or grid and the winding Lfn is connected to the filter capacitor Cfn characterized in that the magnetic core (2) is a closed magnetic core and said windings LINn, LOUTn, Lfn are galvanically insulated.
