Method for producing an inductor
An inductor and a method for producing an inductor are provided where the inductor includes a first core made of a first magnetic material, and at least two windings, configured to be twisted with each other and embedded within the first core, each winding having a pair of terminals extending out of the first core. A method for producing an inductor includes providing a package of the at least two windings twisted and separated from each other, and forming the first core from the first magnetic material over the at least two windings. A method for producing an inductor includes forming a second core from a second magnetic material over the first core.
1 . A method for producing an inductor, the method comprising the following steps:
1) Providing a package of at least two windings twisted and separated from each other; and
2) forming a first core from a first magnetic material over the at least two windings;
wherein the inductor has the first core made of the first magnetic material and the at least two windings being twisted around each other along their entire winding length and entirely embedded within the first core, each winding comprising a pair of terminals extending out of the first core.
2 . The method according to claim 1 , further comprising:
forming the pair of terminals for each of the windings before the step 2) of forming the first core.
3 . The method according to claim 1 , further comprising:
forming cooling passage for at least one of the windings.
4 . The method according to claim 1 , wherein at least one of the steps is performed by a 3D-printing technique, a casting technique or an assembling technique.
5 . A method for producing an inductor, the method comprising the following steps:
1) Providing a package of at least two windings twisted and separated from each other;
2) Forming a first core from a first magnetic material over the at least two windings; and
3) forming a second core from a second magnetic material over the first core;
wherein the inductor has:
the first core made of the first magnetic material;
the at least two windings being twisted around each other along their entire winding length and entirely embedded within the first core, each winding having a pair of terminals extending out of the first core; and
the second core enclosing the first core, wherein the second core is made of a second magnetic material having a higher magnetic permeability than that of the first magnetic material, and the terminals of the windings extend out of the second core.
