Flyback protection diode
WebSep 27, 2010 · Sep 24, 2010. #12. The flyback voltage from a switched inductor does not appear on the supply rail. It appears on the switched side of the inductor. Also, the protection diode peak current will not exceed the magnitude of the current that was flowing through the inductor when it was switched off. J. WebFeb 25, 2024 · Diodes in a “flyback” configuration provide a simple solution: electricity flows in the proper direction across the inductor when in operation, then moves in a reverse path across the diode’s forward …
