Flyback secondary snubber
WebThe regenerative snubber for flyback converter presented in [17,18] differs from the LC snubber, because it is based on three coupled inductors rather than the regular two coupled inductors or two winding transformer. The third coupled inductor or the auxiliary inductor is used as a snubber inductor instead of using a separate inductor like LC ... WebAug 7, 2014 · Designing an RDC snubber for flyback converter. Figure 1 shows a Flyback converter with some critical parasitic components, such as L lk — the primary leakage inductance of the transformer — and C oss …
