Webto the flyback controller (U1) while the transformer is being energized. Figure 3-1 shows the switching wave form of DCM flyback converter operating near critical conduction. In this figure DRV is the logic level of the flyback controllers gate driver and CS is the voltage measured across the current sense resistor (R. CS). When the
WebThe ringing B is caused by operating in DCM, and it is the oscillation of the transformer primary inductance resonance with MOSFET Coss. This is a natural behavior at light load, unless you use synchronous rectifier (FET) to replace the diode rectifier on the secondary side. Hope this clarifies.
