Aiming at the requirement of the high power PECC power supply and raising the transformation efficiency,a kind of two-transistor flyback converter is designed to work in the discontinuous conduction mode,which pulse frequency and width can be independently modulated as well as the pulse energy and interval of every output current pulse are controlled well.

Detailed operation of the secondary side post regulation application in flyback converter is discussed.
