Snubber Circuit Flyback. Suppression circuits voltage snubbers that can be used to suppress these transients on both the primary and secondary side. Once v sn is determined the power dissipated in the snubber circuit at the minimum input voltage and full load condition is obtained by.
The snubber capacitor voltage vsn should be determined at the minimum input voltage and full load condition. However there are special cases when a snubber circuit is not needed resulting in an even more simplified schematic and a smaller solution footprint. The flyback topology figure 1a results in significant cost and space savings for multiple output power supplies with high output voltage for power levels up to 100w.
Once v sn is determined the power dissipated in the snubber circuit at the minimum input voltage and full load condition is obtained by.
Vsn should be 2 2 5 times of nvo. Where fs is the switching frequency of the flyback converter. A snubber circuit is generally recommended when using the high voltage lt8304 to protect the switch node. The flyback topology figure 1a results in significant cost and space savings for multiple output power supplies with high output voltage for power levels up to 100w.
