Abstract
A transformer includes a primary side module, a secondary winding structure, and a magnetic core assembly. The primary side module includes a primary winding structure, a first covering structure and a second covering structure. The primary winding structure has a first opening. The first covering structure includes a second opening corresponding to the first opening and a first receiving recess for accommodating the primary winding structure. The first receiving recess is covered and sealed by the second covering structure. The second covering structure includes a third opening corresponding to the first opening. The first opening, the second opening and the third opening are in communication with each other to be defined as a channel. The secondary winding structure includes a fourth opening, which is in communication with the channel. The magnetic core assembly is partially embedded within the channel and the fourth opening.
