"WebNov 3, 2016 · It's all related to flyback action itself. Flyback action cannot be initiated and completed, because there's no load. Remember how flyback converters work: Energy stored in primary winding will be transfer to the "load". No load, no transfer, no flyback action. The solution is putting a "dummy load" in the converter. " - Flyback ringing

WebMay 25, 2024 · This ringing is primarily due to T1’s magnetizing inductance and to the parasitic capacitances of Q1, D1, and T1. This is easily seen in Q1’s drain voltage during t3, which drops from VIN plus the reflected output voltage back to VIN, since T1 cannot support a voltage once current flow stops. WebThe self-oscillating flyback converter is a robust, low component count circuit that has been widely used in low power off-line applications.
