Abstract

An inductor assembly for use in a power converter for transferring power between a DC voltage network and a multiphase AC voltage network.The inductor assembly comprises a core for guiding magnetic flux and coils for generating magnetic flux wherein the core has first legs with differential mode coil wires wound around the first legs and at least one second leg with at least two common mode coil wires wound around said second leg. The winding direction of both AC- and DC-side coils is such that a common-mode electrical current which flows in both coils in the same direction induces in each core leg a magnetic flux which reinforces the total flux circulating in the core.
