摘要:
A coil form (1) displaying a low inter-winding capacitance comprises a bobbin (4) made of an electrically insulating material (5) and including a tube section shaped wall (6); and a coil mechanically supported by the bobbin (4) and including both a first plurality (11) of conductor windings on the outside of the wall (6) and a second plurality (13) of conductor windings on the inside of the wall (6).
摘要:
The invention relates to an inductance device (30) for a power converter (10) comprising a core (21) with a first leg (21a), a second leg (21 b) oriented parallel to the first leg (21a), a third leg (21c) and a fourth leg (21d), wherein the legs (21a, 21b, 21c, 21d) are in a rectangular arrangement. A first winding (22a) is wound around the first leg (21 a) and a second winding (22b) is wound around the second leg (21b).The inductance device (30) further comprises a third winding (31) comprising a short-circuited wire and being wound around an outer perimeter of the inductance device (10) as defined by the outer surfaces of the first winding (22a) and the second winding (22b), wherein a winding axis of the third winding (31) is oriented parallel to the first leg (21 a) and the second leg (21 b) of the core (21). The inductance device (30) may form part of a power converter (10) or a filter device (17) for a power converter.
