Abstract

Disclosed is a power supply apparatus. The power supply apparatus includes a first magnetic core; a second magnetic core having a shape equal to a shape of the first magnetic core; a third magnetic core between the first and second magnetic cores; a first coil wound around one of the first and third magnetic cores; and a second coil wound around one of the second and third magnetic cores.

Description

[0001] Cross References to Related Patents [0002] This application claims priority from Korean Patent Application No. 10-2011-0077639 filed on Aug. 4, 2011, the entire contents of which are hereby incorporated by reference. technical field [0003] The present invention relates to power supply equipment. Background technique [0004] Recently, electronic products have various functions and excellent performance, and have been developed toward small size and light weight. In order to realize electronic products having a small size and light weight, it is necessary to reduce the size or volume of parts mounted in the electronic products. [0005] In particular, with the development of semiconductor integrated circuits, circuits can be fabricated with small size and light weight. However, there is a problem of reducing the volume of inductors mounted in electronic products. In this regard, studies and researches have been continuously conducted to reduce the size and weigh...
