A planar transformer, comprising:
- a core provided to induce formation of a magnetic field;
- a bobbin coupled to the core;
- at least one primary winding interposed between the core and the bobbin to supply a power signal;
- a first insulation unit provided to the at least one primary winding to insulate the at least one primary winding;
- at least one secondary winding provided to the first insulation unit and insulated by the first insulation unit to transform the power signal;
- and
- a second insulation unit provided to the at least one secondary winding to insulate the at least one secondary winding;
- wherein the core includes a first fastening lug and a second fastening lug distanced from the first fastening lug;
- wherein the bobbin includes a first fastening hole to be coupled to the first fastening lug and a second fastening hole to be coupled to the second fastening lug;
- and
- wherein the first fastening lug is formed with a geometric shape different from that of the second fastening lug.
