Self-driven synchronous rectifier circuit
Source: InternetPublisher:小胖友 Keywords: Synchronous rectifier Updated: 2021/10/09
VSEC is the secondary side voltage of the transformer, and Vgs is the driving voltage of the synchronous rectifier obtained from the auxiliary winding . It can be seen that even during the dead time, the driving voltage of the synchronous rectifier cannot be zero, ensuring that the self- driving method is applications in this topology.
