MAGNETIC CORE

摘要

A magnetic core utilized in a reactor includes an upper yoke, a bottom yoke, and at least two core columns. The closed magnetic loop is formed by the upper yoke, the bottom yoke, and the core columns. The core columns include at least one first magnetic column. The first magnetic column includes a core body, a balance magnetic unit and an air gap. The balance magnetic unit and the adjacent air gap form a composite air gap for dividing the first magnetic column into different parts. The upper yoke, the bottom yoke, and the two core columns constitute a closed magnetic loop. The composite air gap is disposed at a side of the core body. The upper yoke, the bottom yoke, and the core body are made of planar laminated magnetic material. The magnetic permeability of the balance magnetic unit is lower than which of the planar laminated magnetic material.

1. A magnetic core utilized in a reactor, comprising:
an upper yoke; a bottom yoke; and at least two core columns comprising at least one first magnetic column, wherein the first magnetic column includes a core body, a balance magnetic unit and an air gap, wherein the balance magnetic unit and the adjacent air gap form a composite air gap for dividing the core body into different parts; wherein the upper yoke, the bottom yoke, and the two core columns essentially constitute a closed magnetic loop, wherein the upper yoke, the bottom yoke, and the core body are made of planar laminated magnetic material, and wherein the magnetic permeability of the balance magnetic unit is lower than the magnetic permeability of the planar laminated magnetic material.
