Power supply unit

摘要

The present invention relates to a power supply unit. According to an embodiment of the present invention, a transformer includes: a magnetic core; a first coil unit which is disposed within the magnetic core and includes a lamination substrate on which a first layer having a conductive pattern is formed to be laminated; and a second coil unit which includes a conductive wire having an insulating distance with the conductive pattern of the lamination substrate. The insulating distance is secured by an insulating layer to be combined with at least one among the first and second coil units.
