Webturns ratios. Often transformers with a 1:1 or 1:1.5 turns ratio can be used. Transformers with matching turns ratios are often smaller. Flyback designs, by contrast, often have hugely mismatched turns ratios. For all its advantages and simplicity, Fly-Buck converter performance tends to deteriorate as power levels increase. Because of the passive WebA flyback converter stores energy in the magnetic field in the transformer air gap during the time the converter switching element (transistor) is conducting. When the switch turns off, the stored magnetic field collapses and the energy is transferred to the output of the flyback converter as electric current.
