Flyback clamp
WebFlyback definition, the return to its starting point of the electron beam in a cathode ray tube, as after the completion of a line in a television picture or of a trace in an oscilloscope. … WebSep 5, 2024 · The active-clamp flyback is another version of flyback that reclaims the leakage energy and at the same time can provide zero voltage switching. The active clamp flyback is more complicated and requires a specialized controller, such as the UCC28780, making it worthy of its own Power Tip, so I’ll save that discussion for later.
