  2. Voltage converter - Wikipedia

    en.wikipedia.org/wiki/Voltage_converter

    Voltage converters can be used in vehicles with 12 V DC outlets. A simple voltage dropper can be used to reduce the voltage for low-power devices; if more than 12V is required, or for high-powered devices, a switched-mode power supply is used.

  3. Three-prong adaptor - Wikipedia

    en.wikipedia.org/wiki/Three-prong_adaptor

    The ground tab is designed to be attached to the outlet faceplate screw, which is supposed to be connected to the building electrical ground. A cheater plug, AC ground lifter or three-prong/two-prong adapter is an adapter that allows a NEMA 5-15P grounding-type plug (three prongs) to connect to a NEMA 1-15R non-grounding receptacle (two slots).

  4. Electric power conversion - Wikipedia

    Conversely, internal 400 Hz internal power may be converted to 50 Hz or 60 Hz for convenience power outlets available to passengers during flight. 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.

    en.wikipedia.org/wiki/AC_power_plugs_and_sockets

    BS 546, "Two-pole and earthing-pin plugs, socket-outlets and socket-outlet adaptors for AC (50-60 Hz) circuits up to 250 V" describes four sizes of plug rated at 2 A, 5 A (Type D), 15 A (Type M) and 30 A. The plugs have three round pins arranged in a triangle, with the larger top pin being the earthing pin.

  7. Power management integrated circuit - Wikipedia

    en.wikipedia.org/wiki/Power_management...

    Power management ICs are solid state devices that control the flow and direction of electrical power. Many electrical devices use multiple internal voltages (e.g., 5 V, 3.3 V, 1.8 V, etc.) and sources of external power (e.g., wall outlet, battery, etc.), meaning that the power design of the device has multiple requirements for operation. A PMIC ...

  9. Buck converter - Wikipedia

    en.wikipedia.org/wiki/Buck_converter

    A buck converter or step-down converter is a DC-to-DC converter which decreases voltage, while increasing current, from its input to its output . It is a class of switched-mode power supply . Switching converters (such as buck converters) provide much greater power efficiency as DC-to-DC converters than linear regulators , which are simpler ...
