Abstract: A multi-phase inductor includes a core made of a magnetic material; at least two phase windings surrounding the core for inducing a magnetic field in the core, such that a common mode inductance (LCM) is provided for the at least two phase windings; and an adjustment member made of a magnetic material, which adjustment member has at least two legs, which are interconnected with each other at an inner end and which are touching the core at an outer end to provide a differential mode inductance (LDM) for the at least two phase windings; wherein the outer end of each leg of the adjustment member overlays an axial side of the core and/or each leg of the adjustment member has a varying thickness between the inner end and the outer end to adjust the differential mode inductance (LDM).

Abstract: A power electronic converter includes a plurality of converter cells, each comprising an inductive power transfer stage having a coupled inductor coupling first and second sides of the converter cell, wherein the inductor comprises a first winding around a first magnetic core and a second winding around a second magnetic core; wherein the first winding and the first magnetic core are separated from the second winding and the second magnetic core by a flat electric insulation layer that provides electric insulation between the first and second sides of the converter cell; wherein at least two of the coupled inductors are arranged so that their insulation layers form a single contiguous insulation layer.
