  2. Insulated-gate bipolar transistor - Wikipedia

    en.wikipedia.org/wiki/Insulated-gate_bipolar...

    The IGBT accounts for 27% of the power transistor market, second only to the power MOSFET (53%), and ahead of the RF amplifier (11%) and bipolar junction transistor (9%). [35] The IGBT is widely used in consumer electronics, industrial technology, the energy sector, aerospace electronic devices, and transportation.

  3. Welding power supply - Wikipedia

    en.wikipedia.org/wiki/Welding_power_supply

    A welding power supply is a device that provides or modulates an electric current to perform arc welding. [1] There are multiple arc welding processes ranging from Shielded Metal Arc Welding (SMAW) to inert shielding gas like Gas metal arc welding (GMAW) or Gas tungsten arc welding (GTAW).

    Winter brings less daylight and colder temperatures, which can disrupt sleep. Seasonal Affective Disorder (SAD) is more common in winter due to the lack of sunlight, causing sleep disturbances.

  9. Bootstrapping (electronics) - Wikipedia

    en.wikipedia.org/wiki/Bootstrapping_(electronics)

    An N-MOSFET/IGBT needs a significantly positive charge (V GS > V th) applied to the gate in order to turn on. Using only N-channel MOSFET/IGBT devices is a common cost reduction method due largely to die size reduction (there are other benefits as well). However, using nMOS devices in place of pMOS devices means that a voltage higher than the ...
