In which the resonant circuit has a transformer. The bridge-type converter connects with a primary side of the transformer, and operates open or close according to a switching signal. The synchronous rectification circuit further includes a pair of rectification transistors and driving circuits. The driving circuits correspondingly connect with channels to the rectification transistors, and respectively examine the current passing through the rectification transistors. A sensing signal is then generated. In accordance with the switching signal and the sensing signal, a driving signal is generated for driving the rectification transistor.

摘要： A center-tapped transformer includes tubular first and second spools, a primary winding unit, and first and second secondary winding units. The first spool has a first surrounding wall, a first pin-mounting wall, and a first pin set mounted on the first pin-mounting wall. The second spool has a second surrounding wall, a second pin-mounting wall, and a second pin set mounted on the second pin-mounting wall. The second surrounding wall has an inner diameter larger than an outer diameter of the first surrounding wall. The primary winding unit is wound on one of the first and second surrounding walls. The first and second secondary winding units are wound on the other one of the first and second surrounding walls.

摘要： 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.
