  2. Power supply - Wikipedia

    en.wikipedia.org/wiki/Power_supply

    An external power supply, AC adapter or power brick, is a power supply located in the load's AC power cord that plugs into a wall outlet; a wall wart is an external supply integrated with the outlet plug itself. These are popular in consumer electronics because of their safety; the hazardous 120 or 240 volt main current is transformed down to a ...

  3. Regulated power supply - Wikipedia

    en.wikipedia.org/wiki/Regulated_power_supply

    A regulated power supply is an embedded circuit; it converts unregulated AC (alternating current) into a constant DC. With the help of a rectifier it converts AC supply into DC. Its function is to supply a stable voltage (or less often current), to a circuit or device that must be operated within certain power supply limits.

  4. Switched-mode power supply - Wikipedia

    en.wikipedia.org/wiki/Switched-mode_power_supply

    Stand-alone switched-mode power supply An adjustable switched-mode power supply for laboratory use. A switched-mode power supply (SMPS), also called switching-mode power supply, switch-mode power supply, switched power supply, or simply switcher, is an electronic power supply that incorporates a switching regulator to convert electrical power efficiently.

  5. Three-phase electric power - Wikipedia

    en.wikipedia.org/wiki/Three-phase_electric_power

    In a symmetric three-phase power supply system, three conductors each carry an alternating current of the same frequency and voltage amplitude relative to a common reference, but with a phase difference of one third of a cycle (i.e., 120 degrees out of phase) between each. The common reference is usually connected to ground and often to a ...

  6. Flyback converter - Wikipedia

    en.wikipedia.org/wiki/Flyback_converter

    Low-power switch-mode power supplies (cell phone charger, standby power supply in PCs) Low-cost multiple-output power supplies (e.g., main PC supplies <250 W [ citation needed ] ) The flyback converter is commonly used at the 50 to 100 W power range, as well as in highvoltage power supplies for televisions and computer monitors - Fundamentals ...

  7. Rectifier - Wikipedia

    en.wikipedia.org/wiki/Rectifier

    The primary application of rectifiers is to derive DC power from an AC supply (AC to DC converter). Rectifiers are used inside the power supplies of virtually all electronic equipment. AC/DC power supplies may be broadly divided into linear power supplies and switched-mode power supplies. In such power supplies, the rectifier will be in series ...

  8. Power supply unit (computer) - Wikipedia

    en.wikipedia.org/wiki/Power_supply_unit_(computer)

    Entry-Level Power Supply Specification (EPS) is a power supply unit meant for high-power-consumption computers and entry-level servers. Developed by the Server System Infrastructure (SSI) forum, a group of companies including Intel, Dell, Hewlett-Packard and others, that works on server standards, the EPS form factor is a derivative of the ATX ...

  9. Electric power system - Wikipedia

    en.wikipedia.org/wiki/Electric_power_system

    A steam turbine used to provide electric power. An electric power system is a network of electrical components deployed to supply, transfer, and use electric power. An example of a power system is the electrical grid that provides power to homes and industries within an extended area.
