TRANSFORMER
A transformer includes a stacked structure in which a plurality of coils is stacked through insulation layers. The stacked structure includes: a primary coil stacked layer including a plurality of primary coil layers connected in parallel with one another; and a secondary coil stacked layer including a plurality of secondary coil layers connected in parallel with one another. One of the primary coil layers is disposed as an outermost layer in the stacked structure, and another is disposed between at least two layers of the plurality of secondary coil layers. The primary coil layer includes a plurality of primary coils connected in parallel with one another. The secondary coil layer includes one or more secondary coils thicker than the primary coil.
1 . A transformer comprising:
a stacked structure in which a plurality of coils is stacked through insulation layers,
wherein the stacked structure comprises:
a primary coil stacked layer comprising a plurality of primary coil layers connected in parallel with one another; and
a secondary coil stacked layer comprising a plurality of secondary coil layers connected in parallel with one another,
wherein one of the primary coil layers is disposed as an outermost layer in the stacked structure, and another is disposed between at least two layers of the plurality of secondary coil layers,
wherein the primary coil layer comprises a plurality of primary coils connected in parallel with one another, and
wherein the secondary coil layer comprises one or more secondary coils thicker than the primary coil.
2 . The transformer according to claim 1 ,
wherein the secondary coil layer comprises a plurality of the secondary coils connected in parallel with one another, and
wherein a number of parallel connections of the primary coils in the primary coil layer is equal to or greater than a number of parallel connections of the secondary coils in the secondary coil layer.
