Flyback converter snubber

WebA simple boost and a fly-forward converter are used to increase the output voltage. A snubber circuit is used for the main switch to recover the energy of the snubber capacitor. Therefore, the main switch turns off at low voltage and it causes a reduction in turn off loss. WebOct 29, 2015 · The proposed snubber has been successfully applied to an example of a 200W, 380V/24V, 100kHz two-switch flyback converter operating in continuous conduction modes and experimental results are in good agreement with the theoretical predictions. 64 View 1 excerpt, references methods
