WebSep 5, 2024 · These variations of the flyback converter use nondissipative clamping techniques to recycle leakage energy and improve efficiency. In the standard form of a flyback converter, the leakage inductance of the transformer creates a voltage spike on the drain of the primary field-effect transistor (FET). WebThe terms flyback or kickback originate from the induced voltage reversal that occurs when the supply current is interrupted. The reversed induced voltage (s) tries to create ( induce ) a current flow. The open switch prevents current from flowing through the power supply. is clicking links dangerous
