Abstract: An inductor assembly includes at least one inductor coil, a metallic inductor housing at least partially enclosing the inductor coil, and a potting material both contacting the inductor coil and the metallic inductor housing and thermally coupling the inductor coil to the metallic inductor housing. The inductor coil includes a bobbin made of electrically insulating material, and an inductor winding made of an electric conductor wound on the bobbin. The inductor winding further has an outer circumference and two end faces, and an electric insulation covers the outer circumference of the inductor winding. Coil lids made of electrically insulating material at least partially cover the end faces of the inductor winding and adjacent areas of the electric insulation covering the outer circumference of the inductor winding such that a distance of any point of the end faces of the inductor winding to the metallic housing along any way not passing through the electrically insulating material of the coil lids or the bobbin is at least a required minimum creepage distance.

Abstract: The disclosure relates to an integral inductor arrangement with at least three magnetic loops arranged side by side to each other in a row and at least one winding associated with each of the magnetic loops. The magnetic loops are formed by individual core elements, each of which being part of one of the magnetic loops, and shared core elements, each of which being part of two adjacent of the magnetic loops. The shared core elements are separated from the individual core elements by magnetic gaps and each of the at least one winding is arranged around one of the individual core elements. The disclosure further relates to a use of such integral inductor arrangement within a 3-phase AC-filter for a power inverter for feeding electrical power into a power grid.
