ABSTRACT:
Disclosed is a transformer having a multilayered winding structure. The transformer is supplied with alternating current power, and transfers the power to another circuit by electromagnetic induction. The transformer includes a core section having a hollow section, and primary and secondary windings isolated electrically from each other and wound around the core section. Each of the primary and secondary windings has a multilayered structure in which a plurality of metal plates are laminated with gaps therebetween and are coupled to each other at one side ends thereof, and the metal plates of the primary and secondary windings are inserted into and coupled to each other at the other side ends thereof in such a manner that the metal plates of the primary winding are alternately inserted into the gaps of the second windings. Thereby, it is possible to greatly reduce conduction loss generated from a high-frequency and high-capacity transformer, to improve voltage conversion efficiency, to greatly reduce an amount of discharging heat generated from the windings, and to efficiently discharge heat.
