Problems solved by technology

[0007] However, there is a problem that the winding work requires an expensive winding device and a skilled technique, and it takes a lot of effort and time to perform the work
In addition, due to the volume expansion due to the end turns of the coil turns, various problems have arisen such as short circuits, edges, or vibrations caused in the coil turns
[0008] In order to solve these problems, a transformer using a printed circuit board (PCB) has been developed, but a planar transformer using such a PCB has a problem that a sufficient transformer capacity cannot be obtained

Abstract

The invention provides a transformer using a printed circuit board and a manufacturing method thereof. The transformer includes a core portion having a magnetic property and having a through hole formed therein, and a first coil portion formed with a first circuit board on which circuit patterns are printed on one surface thereof, having a shape enclosing a part of the core portion while penetrating the through hole of the core portion, and formed to be bent so that both side end portions of the first circuit board are connected to each other.

Description

technical field [0001] The present disclosure relates to a transformer including a printed circuit board and a method of manufacturing the same, and more particularly, to a three-dimensional transformer formed by bending a planar printed circuit board. Background technique [0002] A transformer is a device used to further increase or decrease AC voltage based on the principle of electromagnetic induction. Two primary and secondary coils are wound around the magnetic core, and when an AC voltage is applied to the primary coil, a change in magnetic flux due to the AC current occurs, which again causes induced electromotive force in the secondary coil. The magnitude of the electromotive force induced in the secondary coil and the number of coil turns have the following relationship. [0003] V2 / V1=N2 / N1 [0004] In this paper, V1 refers to the supply voltage of the primary coil, V2 refers to the induced electromotive force of the secondary coil, N1 refers to the number of tu...
