Integrated magnetic component

摘要

A magnetic component, with a first and a second U/UR core (U1, U2) assembled to a first O-shaped core assembly, wherein an U/UR core has—according to its shape—a first post and a second post with free ends on one side and a leg connecting the first post and the second post on their other side, wherein the first and the second U/UR core (U1, U2) are assembled with their free ends abutting each other to form the first O-shaped core assembly. The free ends of a third U/UR core (U3) are abutting the outside of the first O-shaped core assembly on one side and that the free ends of a fourth U/UR core (U4) are abutting the outside of the first O-shaped core assembly on an opposite side. In another embodiment, the leg of a third U/UR core (U3) is abutting the outside of the first O-shaped core assembly, wherein the ends of a fourth U/UR core (U4) are abutting the ends of the third U/UR core (U3). In a further embodiment, the ends of a third U/UR core (U3) are abutting the outside of the first O-shaped core assembly. At least one winding is wound directly on the first, the second, the third, and/or the fourth U/UR core (U1, U2, U3, U4). The core structure can either be fully composed of high permeability low saturation cores with air gaps or be composite comprising low permeability high saturation cores and high permeability low saturation cores with no air gaps.

主权项

1. An integrated magnetic component, comprising:
a first, a second and a third U core or UR core, wherein each core has a first post and a second post with free ends on one side and a leg connecting the first post and the second post on their other side, wherein the first and the second core are assembled with their free ends abutting each other to form a first O-shaped core assembly, and the free ends of the third core are abutting the outside of the first O-shaped core assembly on one side, wherein at least one of the first, second, or third cores is a pre-manufactured standardized building block, the core of each pre-manufactured standardized building block is bobbin less and includes a winding wound directly on its leg such that each turn of said winding encompasses just said leg; and a fourth U core or UR core having a first post and a second post with free ends on one side and a leg connecting the first post and the second post on their other side, wherein the free ends of the fourth U core or UR core are abutting the outside of the first O-shaped core assembly on a side opposite to the third core.
