Abstract

Disclosed herein is a transformer including: an iron core; and a winding wound around the iron core; wherein the iron core includes a column-shaped output side iron core part, a plurality of column-shaped input side iron core parts, and a connecting iron core part, the winding includes a plurality of primary windings, a secondary winding, and generated magnetic fluxes.

Claims

1. A transformer comprising:

an iron core; and

a winding wound around said iron core;

wherein said iron core includes

a column-shaped output side iron core part,

a plurality of column-shaped input side iron core parts situated in a vicinity of said output side iron core part, and

a connecting iron core part configured to connect both ends in a direction of length of said plurality of input side iron core parts to both ends in a direction of length of said output side iron core part,

said winding includes

a plurality of primary windings respectively wound around said plurality of input side iron core parts,

a secondary winding wound around said output side iron core part, and

generated magnetic fluxes generated in said input side iron core parts by said primary windings, respectively, independently pass through said output side iron core part via said connecting iron core part, whereby a total of a plurality of said generated magnetic fluxes intersect said secondary winding.

2. The transformer as claimed in claim 1,

wherein said input side iron core parts and said output side iron core part are arranged in parallel with each other.

3. The transformer as claimed in claim 1,

wherein said input side iron core parts and said output side iron core part are arranged in parallel with each other, and are disposed in a shape of extending straight lines arranged in a direction orthogonal to the direction of length of said input side iron core parts and said output side iron core part.

4. The transformer as claimed in claim 1,

wherein said plurality of input side iron core parts is disposed around said output side iron core part.

5. The transformer as claimed in claim 1,

wherein said output side iron core part is formed by a plurality of column bodies, and said secondary winding is wound around said plurality of column bodies.
