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.

Abstract: A power supply system includes a power feeding system for transforming an AC medium-voltage power signal from a medium-voltage grid into a low-voltage power signal for feeding an electricity consumer site. The power supply system further includes a low-voltage multiphase converter for transforming a low-voltage signal into a low-voltage multiphase signal. The multiphase converter is arranged antiparallel to the power feeding system, and an LV/MV multiphase transformer for transforming the low-voltage multiphase signal into an output-signal that is conformant to the AC medium-voltage power signal.
