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.
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 being 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, wherein the shared core elements are separated from the individual core elements by magnetic gaps which are arranged each between a respective end surface of an individual core element and a respective side surface of an end section of a shared core element, and each of the at least one winding is arranged around one of the individual core elements and not arranged around the magnetic gaps, wherein each of the at least one winding defines a respective one of the magnetic loops, and further wherein the magnetic gaps comprise dielectrics, air gaps or magnetic materials having a lower permeability than the individual or shared core elements.
