<p>The present invention relates to a flyback converter using a coaxial cable transformer, and the flyback converter using the coaxial cable transformer according to one embodiment of the present invention comprises: a flyback driving unit which supplies a primary current; a transformer which winds, on a magnetic core, cables having a plurality of inner core wires as primary cables and outer core wires for enclosing the plurality of the inner core wires as secondary cables, and is formed by connecting both ends of the primary cables in serial, and then receives the primary current to output a secondary current according to turn ratios of the primary cables and the secondary cables; a rectifying diode which rectifies the secondary current; and an output capacitor which smoothes a voltage through the rectifying diode. Thus, since the coaxial cable transformer included in the flyback converter is manufactured by using multi-core coaxial cables, a coupling coefficient is improved and leakage inductance is minimized, thereby enhancing power efficiency.</p> |
