  2. Flyback diode - Wikipedia

    en.wikipedia.org/wiki/Flyback_diode

    Diagram of a simple circuit with an inductance L and a flyback diode D.The resistor R represents the resistance of the inductor's windings. A flyback diode is any diode connected across an inductor used to eliminate flyback, which is the sudden voltage spike seen across an inductive load when its supply current is suddenly reduced or interrupted.

    en.wikipedia.org/wiki/ULN2003A

    ULN2003A pinout Simplified ULN2003A logical pinout diagram. The ULN2003A is an integrated circuit produced by Texas Instruments. It consists of an array of seven NPN Darlington transistors capable of 500 mA, 50 V output. It features common-cathode flyback diodes for switching inductive loads (such as servomotors).

  4. Flyback converter - Wikipedia

    en.wikipedia.org/wiki/Flyback_converter

    The flyback converter is used in both AC/DC, and DC/DC conversion with galvanic isolation between the input and any outputs. The flyback converter is a buck-boost converter with the inductor split to form a transformer, so that the voltage ratios are multiplied with an additional advantage of isolation.

  7. Forward converter - Wikipedia

    en.wikipedia.org/wiki/Forward_converter

    The flyback converter can be viewed as two inductors sharing a common core with opposite polarity windings. In contrast, the forward converter (which is based on a transformer with same-polarity windings, higher magnetizing inductance, and no air gap) does not store energy during the conduction time of the switching element — transformers ...

  8. Single-ended primary-inductor converter - Wikipedia

    en.wikipedia.org/wiki/Single-ended_primary...

    Fast conventional diodes or Schottky diodes may be used. The resistances in the inductors and the capacitors can also have large effects on the converter efficiency and output ripple. Inductors with lower series resistance allow less energy to be dissipated as heat, resulting in greater efficiency (a larger portion of the input power being ...

  9. Talk:Flyback diode - Wikipedia

    en.wikipedia.org/wiki/Talk:Flyback_diode

    In the flyback switcher, the flyback is desired; the goal is not to snub or suppress or eliminate the flyback. The typical reverse-biased diode across inductor can suppress the flyback, but it keeps the current flowing with little loss. The circuit is a problem when trying to turn the magnetic field off quickly.
