Abstract
Official abstract text for this publication.
The present invention concerns a multiphase system comprising a power converter having at least two legs and a filtering device connected to the at least two legs of the power converter, the filtering device being composed of at least two inductors, each inductor being composed of turns wounded around a magnetic material. The magnetic material is disposed within at least one printed circuit board that comprises connections of the inductors and the filtering device further comprises a conductive material surrounding the at least two inductors, a first terminal of each inductor being respectively connected to one leg of the power converter and one terminal of the conductive material is connected to the second terminals of the inductors.

1 . A multiphase system comprising a power converter having at least two legs and a filtering device connected to the at least two legs of the power converter, the filtering device being composed of at least two inductors, each inductor being composed of turns wounded around a magnetic material, characterized in that the magnetic material is disposed within at least one printed circuit board that comprises connections of the inductors and the filtering device further comprises a conductive material surrounding the at least two inductors, a first terminal of each inductor being respectively connected to one leg of the power converter and one terminal of the conductive material is connected to the second terminals of the inductors. 2 . The multiphase system according to claim 1 , characterized in that the filtering device comprises one printed circuit board having at least two cavities wherein each of the at least two magnetic materials is respectively placed. 3 . The multiphase system according to claim 2 , characterized in that the printed circuit board further comprises for each cavity, two spaces for wounding the inductors around the magnetic core. 4 . The multiphase system according to claim 2 , characterized in that the printed circuit board further comprises for each cavity, two spaces for inserting the wounded inductors around the magnetic core and the magnetic core. 5 . The multiphase system according to claim 1 , characterized in that the filtering device comprises a first, a second and a third printed circuit boards, the third printed circuit board having at least two cavities wherein each of the at least two magnetic materials is respectively placed, the first and the second printed circuit boards having conductors, the conductors of the first and the second printed circuit boards being electrically connected and form windings of the inductors. 6 . The multiphase system according to claim 5 , characterized in that the conductive material surrounding the at least two inductors has a U shape. 7 . A method for manufacturing a multiphase system comprising a power converter having at least two legs and a filtering device connected to the at least two legs of the power converter, the filtering device being composed of at least two inductors, characterized in that the method comprises the steps of: disposing magnetic materials within at least one printed circuit board that comprises connections of the inductors, disposing, for each inductor, turns wounded around the magnetic material, placing a conductive material surrounding the at least two inductors, connecting the filtering device by connecting respectively a first terminal of each inductor to one leg of the power converter and connecting one terminal of the conductive material to the second terminals of the inductors.
