Synchronous rectification module

Abstract

The present invention provides a synchronous rectification module. The synchronous rectification module includes a circuit board, a transformer, two synchronous rectification sets and a grounding set. The transformer includes a primary winding and a secondary electrically-conductive foil winding. The first and second synchronous rectification sets are symmetrically disposed on the circuit board, corresponding to the transformer and electrically connected to a secondary dotted end tap and a secondary synonyms end tap of the secondary electrically-conductive foil winding respectively. The secondary electrically-conductive foil winding of the transformer is disposed nearby a lateral edge of the first or second synchronous rectification set, and the grounding set is disposed along a bottom edge of the circuit board and nearby the bottom edge of the first or second synchronous rectification set, so as to reduce the current path of the secondary synchronous rectification circuit and achieve the purposes of miniaturization and high power density.
