  2. Flyback transformer - Wikipedia

    en.wikipedia.org/wiki/Flyback_transformer

    The flyback (the vertical portion of the sawtooth wave) can be a potential problem for the flyback transformer if the energy has nowhere to go: the faster a magnetic field collapses, the greater the induced voltage, which, if not controlled, can flash over the transformer terminals. The high frequency used permits the use of a much smaller ...

    Logo used until 2015. Samsung Galaxy (Korean: 삼성 갤럭시; stylized as SΛMSUNG Galaxy since 2015 (except Japan where it omitted the Samsung branding up until 2023), [2] previously stylized as Samsung GALAXY; abbreviated as SG) is a series of computing, Android mobile computing and wearable devices that are designed, manufactured and marketed by Samsung Electronics since 29 June 2009.

  4. Flyback converter - Wikipedia

    en.wikipedia.org/wiki/Flyback_converter

    Fig. 1: Schematic of a 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. Electric power conversion - Wikipedia

    en.wikipedia.org/wiki/Electric_power_conversion

    Certain specialized circuits can also be considered power converters, such as the flyback transformer subsystem powering a CRT, generating high voltage at approximately 15 kHz. Consumer electronics usually include an AC adapter (a type of power supply) to convert mains-voltage AC current to low-voltage DC suitable for consumption by microchips.

  8. 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 ...
