WebAug 4, 2010 · A snubber is often needed when the MOSFET is turned off as the transformer's leakage inductance will cause the drain voltage to rise above the reflected output voltage (V reset). The energy stored in the … WebMay 29, 2024 · Figure 5 shows a flyback converter with a snubber circuit. Click image to enlarge. Figure 5: Flyback Converter with an Input Snubber Circuit. For the snubber, the design process is comprised of three stages. First, the leakage inductance is estimated to be about 2% of the primary inductance. Then, a maximum snubber capacitor voltage ripple … WebJun 19, 1994 · Flyback derived power convertor topologies are attractive because of their relative simplicity when compared with other topologies used in low power applications. Incorporation of active-clamp circuitry into the flyback topology serves to recycle transformer leakage energy while minimizing switch voltage stress.
