Abstract
A storage choke is disclosed. In an embodiment a storage choke includes at least two coils and a core, wherein the core couples the coils to one another, and wherein the core comprises a first region comprising a first material and a second region comprising a second material that is different from the first material.
Claims20
A storage choke comprising:
- at least two coils;
- and
- a core,
- wherein the core couples the coils to one another,
- wherein the core comprises a first region comprising a first material, and a second region comprising a second material that is different from the first material, and
- wherein the first material has a higher saturation magnetization than the second material.

A storage choke comprising:
- at least two coils;
- and
- a core,
- wherein the core couples the coils to one another,
- wherein the core comprises a first region comprising a first material, and a second region comprising a second material that is different from the first material, and
- wherein a magnetic saturation of the first material does not occur until magnetic flux densities of more than one tesla are reached.
3 more elements
A storage choke comprising:
- at least two coils;
- and
- a core,
- wherein the core couples the coils to one another,
- wherein the core comprises a first region comprising a first material, and a second region comprising a second material that is different from the first material,
- wherein the first region comprises rod-shaped cores and inner plates, each coil being wound around a rod-shaped core, and
- wherein the rod-shaped cores are arranged between the inner plates and bear directly on the inner plates.
4 more elements
A storage choke comprising:
- at least two coils;
- and
- a core,
- wherein the core couples the coils to one another,
- wherein the core comprises a first region comprising a first material, and a second region comprising a second material that is different from the first material,
- wherein the first region comprises at least one core part, which is arranged between two coils in such a way that a first side surface of the at least one core part faces toward one of the two coils and a second side surface of the at least one core part faces toward another of the two coils.
