Abstract
A reactor part includes at least a winding and a magnetic substance core, in which the core includes a pair of winding portions around each the winding is wound, and a non-winding portion around which no winding is wound, wherein a cross-sectional area in a direction orthogonal to a magnetic path of the non-winding portion of the core is made smaller than a cross-sectional area in a direction orthogonal to a magnetic path of the each of winding portions.
Claims20
A reactor part, comprising:
- at least a winding and a magnetic substance core,
- wherein said core comprises:
- a pair of winding portions around each of which said winding is wound;
- and
- a non-winding portion around which no winding is wound,
- wherein a cross-sectional area of said non-winding portion, located in a centerline of said core, in a direction orthogonal to a magnetic path of said non-winding portion of said core is smaller than a cross-sectional area in a direction orthogonal to a magnetic path of said each of winding portions,
- wherein the cross-sectional area of said non-winding portion is at least 0.67 times of a cross-sectional area of said each of winding portions, and
- wherein said non-winding portion comprises two non-winding portions, each comprising an approximately trapezoidal or triangular magnetic substance block.

A reactor part, comprising:
- at least a winding and a magnetic substance core,
- wherein said core comprises:
- a pair of winding portions around each of which said winding is wound;
- and
- a non-winding portion around which no winding is wound,
- wherein said each of winding portions has at least two magnetic substance blocks each having a rectangular and plane shape arranged in parallel with an interval interposed between one another,
- wherein two non-winding portions, each comprising an approximately trapezoidal or triangular magnetic substance block, are arranged in a manner in which said two approximately trapezoidal or triangular magnetic substance blocks of said non-winding portion sandwich said magnetic substance blocks comprising said each of winding portions by each of approximately trapezoidal or triangular bottoms of said non-winding portions so as to be faced one another,
- wherein a cross-sectional area of said non-winding portion, located in a centerline of said core, in a direction orthogonal to a magnetic path of an approximately trapezoidal or triangular crest portion of each of said magnetic substance blocks making up said non-winding portion is smaller than a cross-sectional area in a direction orthogonal to a magnetic path of each of said magnetic substance blocks making up said each of winding portions, and
- wherein the cross-sectional area of said non-winding portion is at least 0.67 times of a cross-sectional area of said each of winding portions.

A reactor part, comprising:
- a magnetic substance core, comprising:
- a pair of symmetrical winding portions around each of which a winding is wound;
- and
- a pair of non-winding portions around each of which no winding is wound, each of said pair of non-winding portions extending between said pair of symmetrical winding portions,
- wherein a cross-sectional area of said each of non-winding portions, located in a centerline of said core, in a direction orthogonal to a magnetic path of said each of non-winding portions is smaller than a cross-sectional area of said each of winding portions in a direction orthogonal to a magnetic path of said each of winding portions,
- wherein the cross-sectional area of said each of non-winding portions is at least 0.67 times of said cross-sectional area of said each of winding portions, and
- wherein said pair of non-winding portions each comprising an approximately trapezoidal or triangular magnetic substance block.
