Abstract
Disclosed is a planar transformer including a first planar core which is formed of a magnetic substance, a lower secondary winding which is disposed to enclose a first left sill of the first planar core between a first rear sill and a first front sill of the first planar core; a primary winding which is disposed on the lower secondary winding so as to enclose first left and right sills of the first planar core; an upper secondary winding which is disposed on the primary winding to enclose the first left sill of the first planar core; and a second planar core disposed on the upper secondary winding.
Claims19
A planar transformer, comprising:
- a first planar core including a first main body which is formed of a magnetic substance, a first rear sill which is formed at a left rear long side of the first main body, a second rear sill which is formed at a right rear long side of the first main body, a first front sill which is formed at a left front long side of the first main body, a second front sill which is formed at a right front long side of the first main body, a first left sill which is formed at a center portion between the first rear sill and the first front sill, and a first right sill which is formed at a center portion between the second rear sill and the second front sill so as to be spaced apart from the first left sill;
- a lower secondary winding which is disposed to enclose the first left sill of the first planar core between the first rear sill and the first front sill of the first planar core;
- a primary winding which is disposed on the lower secondary winding so as to enclose the first left and right sills of the first planar core;
- an upper secondary winding which is disposed on the primary winding to enclose the first left sill of the first planar core;
- and
- a second planar core including a second main body disposed on the upper secondary winding;
- wherein the first planar core comprises a first vent hole on the first main body, and the second planar core comprises a second vent hole corresponding to the first vent hole.

- an upper secondary winding which is disposed on the primary winding to enclose the first left sill of the first planar core;
- and
- a second planar core including a second main body which have a flat type, and disposed on the upper secondary winding;
- wherein the first planar core comprises a first vent hole on the first main body;
- and
- wherein the first vent hole is formed between the first left sill and the first right sill, and through which air is ventilated to outside.
