Abstract
Disclosed is a flyback converter using a coaxial cable transformer which includes: a flyback driving unit that supplies a primary current; a transformer that is formed by winding a cable, which has a plurality of inner conductors as a primary cable and an outer conductor enclosing the inner conductors as a secondary cable, around a magnetic core and by connecting both ends of the primary cable and that receives the primary current and outputs a secondary current in accordance with the turn ratio of the primary cable and the secondary cable; a rectifying diode that rectifies the secondary current; and an output capacitor that smoothes a voltage through the rectifying diode.

A flyback converter using a coaxial cable transformer, comprising:
- a flyback driving unit that supplies a primary current;
- a transformer that is formed by winding a cable, which has a plurality of inner conductors as a primary cable and an outer conductor enclosing the inner conductors as a secondary cable, around a magnetic core and by connecting both ends of the primary cable in series and that receives the primary current and outputs a secondary current in accordance with the turn ratio of the primary cable and the secondary cable;
- a rectifying diode that rectifies the secondary current;
- and
- an output capacitor that smoothes a voltage through the rectifying diode.
A flyback converter using a coaxial cable transformer, comprising:
- a flyback driving unit that supplies a primary current;
- a transformer that is formed by winding a cable, which has inner conductors formed by twisting a plurality of thin enamel wires with an insulating coating as a primary cable and a coated outer conductor enclosing the inner conductors as a secondary cable, around a magnetic core and by connecting the enamel wires at both ends of the primary cable in series and that receives the primary current and outputs a secondary current in accordance with the turn ratio of the primary cable and the secondary cable;
- a rectifying diode that rectifies the secondary current;
- and
- an output capacitor that smoothes a voltage through the rectifying diode.
