  2. Interferon regulatory factors - Wikipedia

    en.wikipedia.org/wiki/Interferon_regulatory_factors

    Interferon regulatory factors (IRF) are proteins which regulate transcription of interferons (see regulation of gene expression). [1] Interferon regulatory factors contain a conserved N-terminal region of about 120 amino acids, which folds into a structure that binds specifically to the IRF-element (IRF-E) motifs, which is located upstream of the interferon genes.

  3. TL431 - Wikipedia

    en.wikipedia.org/wiki/TL431

    In 2015, Texas Instruments announced the ATL431, an improved derivative of the TL431 for very high efficiency switch-mode regulators [49] that has a V REF of 2.5 V instead of 2.495 V. The recommended minimum operating current is only 35 μA (standard TL431: 1 mA); the maximum I CA and V CA are the same as standard (100 mA and 36 V). [50]

    These generators are equipped with automatic voltage regulators that adjust the excitation field keeping the voltage at the generator's terminals within the target range. [ 7 ] The task of additional reactive power compensation (also known as voltage compensation ) is assigned to compensating devices : [ 7 ]

    en.wikipedia.org/wiki/Power_MOSFET

    NXP 7030AL - N-channel TrenchMOS logic level FET IRF640 Power Mosfet die. The power MOSFET is the most widely used power semiconductor device in the world. [3] As of 2010, the power MOSFET accounts for 53% of the power transistor market, ahead of the insulated-gate bipolar transistor (27%), RF power amplifier (11%) and bipolar junction transistor (9%). [24]

  7. LM317 - Wikipedia

    en.wikipedia.org/wiki/LM317

    As linear regulators, the LM317 and LM337 are used in DC to DC converter applications. Linear regulators inherently waste power; the power dissipated is the current passed multiplied by the voltage difference between input and output. A LM317 commonly requires a heat sink to prevent the operating temperature from rising too high. For large ...

    (The Center Square) - An international regulatory authority issued a warning that California’s energy grid is at risk of energy shortfalls in 2029, noting increased electrification of buildings ...

  9. Ancillary services (electric power) - Wikipedia

    en.wikipedia.org/wiki/Ancillary_services...

    Wind turbines with variable-speed generators have the potential to add synthetic inertia to the grid and assist in frequency control. [7] [8] [9] CAISO tested the 131 MW Tule wind farm's synchronverter in 2018, and found it could perform some of the grid services similar or better than traditional generators.
