SR control in the Flyback topology can be implemented in various ways, ranging from conventional self-driven (secondary winding voltage detection) to a more complex current-driven solution, or a combination of both to improve the existing SR-Flyback topology.
Based on this description, the flyback transformer actually operates as a coupled inductor, where current builds up to a peak value in the primary winding and then decays back down in the secondary winding during the flyback interval.
The avail-ability of sophisticated controller ICs, togeth-er with high-voltage MOSFETs and design support software, enable flyback supplies to meet the most demanding performance and environmental standards. It is anticipated that further developments will push the boundaries of performance and power con-sumption even further in the years to come.
Through power loss analysis on Flyback converters, there are two key power loss factors: the first one is main MOSFET switching loss on the primary side during switch turn-on when the MOSFET has a high drain to source voltage, Vds. And the second is the conduction loss of the secondary side output diode.
Figure 1 illustrates the basic implementation. The flyback converter is derived from buck-boost topology with a mutually-coupled inductor that forms the transformer. The transformer provides a voltage ratio from input to output and the advantage of galvanic isolation.
The SR-Flyback converter is a type of high efficiency synchronous rectifier flyback converter for high density AC/DC applications. Its theory is introduced with main design considerations given.
