摘要： The present invention relates to an arrangement of LCL filter structure and specially a filter structure to be connected to the output of inverter or network converter and to the arrangement of chokes. An arrangement of LCL filter structure comprising three pairs of two chokes (2, 3), (4, 5), (6, 7) per phase U, V, W , respectively. Each of the choke has a winding (10) wound around a yokeless, columnar core (11) having at least two axes X-X, X'-X'. The arrangement is characterize in that the LCL filter structure for a single phase U, V, W has at least one choke with the winding (10) wound around a yokeless, columnar core (11) situated centrally around the other axes Y-Y, Y'-Y'. The axes Y-Y, Y'-Y' are situated parallel to the axes X-X, X'-X' in a such distance that each of the singular chokes of each pair of the chokes is not in contact with any other chokes. A projection of winding (10) wound around the axis Y-Y or Y'-Y', respectively, of at least one choke (4), (5) is overlapped on the other winding (10) of the chokes (3) or (7) arranged around axis X-X or on the other winding (10) of the chokes (2) or (6) arranged around axis X'-X. All pairs of the chokes (2, 3), (4, 5) and (6, 7) are placed inside the shielding enclosure (9) forming one magnetic screen for all chokes together.

摘要： A laminated multi-phase busbar (1) for conducting electric energy, comprising a base layer (2) of an electrically insulating material, a first conducting layer (4a) of an electrically conducting material which is arranged on and mechanically connected to said base layer (2), a first intermediate insulating layer (6a) of an electrically insulating material which is arranged on and mechanically connected to said first conducting layer (4a), a second conducting layer (4b) of an electrically conducting material which is arranged on and mechanically connected to said first intermediate layer (6) and a cover layer (8) of an electrically insulating material which is arranged on said second conducting layer (4b), wherein said electrically insulating material of said base layer (2), said first intermediate insulating layer (6a) and said cover layer (8) is a sheet molding compound including a thermosetting resin and reinforcing fibers, and that the material of said first conducting layer (4a) and said second conducting layer (4b) is a sheet metal which is mechanically connected to the first intermediate insulating layer (6a) by said thermally cured thermosetting resin, is characterized in that said first conducting layer (4a) comprises at least one first through-hole (10a) which is filled with thermosetting resin and reinforcing fibers, said thermosetting resin and reinforcing fibers in said first through-hole (10a) forming a material bridge (12a) bonding said base layer (2) to said first intermediate insulating layer (6a).
