變壓器的一次繞組軸向分裂，可實現兩臺變壓器集成;變壓器的漏抗必然存在，且在一次側與平衡電抗器串聯，在二次側與濾波電容串聯，可以實現幾種磁性器件的集成。因此，變壓器採取磁集成技術將大大降低輔助電源的體積。 -
The principles and characteristics of synchronous rectification ( sr ) are given, and advantages of self - driven sr in low power applications is detailed. review of several topologies which incorporate self - driven sr makes the constrains of conventional self - driven sr scheme apparent and thus a new scheme to drive srs is proposed. the developed single - winding self - driven synchronous rectification ( swsdsr ) scheme works properly in topologies that drive symmetrically the transformer ( push - pull, half bridge, . . ). it allows for maintaining the srs on even when the voltage in the transformer is zero, which is impossible to do in traditional self - driven approaches
