Abstract
A transformer having adjustable leakage inductance includes a primary winding coil, a secondary winding coil, a bobbin and a magnetic core assembly. The bobbin includes a winding section for winding the primary winding coil and the secondary winding coil thereon, wherein the bobbin further includes a channel therein. The magnetic core assembly is partially embedded into the channel of the first bobbin. The primary winding coil and the secondary winding coil are partially overlapped with each other and wound around the winding section of the bobbin to be defined as an overlap region. The region where the primary winding coil and the secondary winding coil are not overlapped with each other is defined as a non-overlap region. The leakage inductance of the transformer is adjusted according to an overlap ratio of the overlap region to the sum of the overlap region and the non-overlap region.
