1. 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 rear sill is spaced apart from the second rear sill, the first front sill is spaced apart from the second front sill, and the first left sill is spaced apart from the first right sill; wherein the first rear sill, the second rear sill, the first front sill, the second front sill, the first left sill, and the second right sill are formed on the first main body; and wherein the first planar core comprises a first vent hole on the first main body. |
