Abstract
There is provided a transformer including an E shaped and two I shaped magnetic cores and a first, second and third windings, wherein: one I shaped magnetic core is located between one side and a middle legs of the E shaped magnetic core, another is located between another side and the middle legs; there is an air gap on each of the two I shaped magnetic cores or two side or bottom legs of the E shaped magnetic core, the first winding is wound on a part of the magnetic cores where the air gap exists; the second and third windings are wound on the middle leg; and the first winding is connected in parallel with the second winding to constitute a primary winding; the third winding is a secondary winding. With the transformer provided by the disclosure, transformer winding loss can be reduced, and transformer efficiency can be improved.
