ABSTRACT:
The present invention relates to a tranformer core structure, which includes a rectangular frame core having two long sides and two short sides, with one short side having a recessed part and the other short side being closed to form a junction surface of magnetic path; and a strip core disposed in the rectangular frame core through the recessed part, and having a length similar to that of said long side of said rectangular frame core, but having a width slightly less than that of said recessed part, wherein adjustment of the inductance of the structure is accomplished by moving said strip core along said recessed part to adjust a gap between one end of said strip core and said junction surface of magnetic path.
