Abstract
A center-tapped transformer includes a spool, a first primary winding unit, and first and second secondary winding units. The spool has a surrounding wall defining a spool axis, and a partition plate unit extending in radial outward directions from the surrounding wall so as to divide the spool into axially extending first and second spool parts. The partition plate unit cooperates with the surrounding wall to define at least one notch. The first primary winding unit surrounds the first spool part and passes through the notch to surround the second spool part. The first and second secondary winding units are disposed on one side of the first primary winding unit and surround the first and second spool parts, respectively.
