  2. Power supply unit (computer) - Wikipedia

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

    The desktop computer power supply converts the alternating current (AC) from a wall socket of mains electricity to a low-voltage direct current (DC) to operate the motherboard, processor and peripheral devices. Several direct-current voltages are required, and they must be regulated with some accuracy to provide stable operation of the computer.

  3. Run-time estimation of system and sub-system level power ...

    en.wikipedia.org/wiki/Run-time_estimation_of...

    Many different approaches (during design of HW, SW or real-time estimation) have been discovered by researchers to estimate power consumption efficiently. This survey paper focuses on the different methods where power consumption can be estimated or measured in real-time.

  4. Maximum power point tracking - Wikipedia

    en.wikipedia.org/wiki/Maximum_power_point_tracking

    Power/Voltage-curve of a partially shaded PV system, with marked local and global MPP. Maximum power point tracking (MPPT), [1] [2] or sometimes just power point tracking (PPT), [3] [4] is a technique used with variable power sources to maximize energy extraction as conditions vary. [5]

  5. 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.

    en.wikipedia.org/wiki/Presentation_program

    LibreOffice Impress, one of the most popular free and open-source presentation programs. In computing, a presentation program (also called presentation software) is a software package used to display information in the form of a slide show. It has three major functions: [1] an editor that allows text to be inserted and formatted

  7. Power supply - Wikipedia

    en.wikipedia.org/wiki/Power_supply

    An integrated power supply is one that shares a common printed circuit board with its load. 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 ...

  9. Switched-mode power supply - Wikipedia

    en.wikipedia.org/wiki/Switched-mode_power_supply

    In contrast, a linear power supply regulates the output voltage by continually dissipating power in the pass transistor. The switched-mode power supply's higher electrical efficiency is an important advantage. Switched-mode power supplies can also be substantially smaller and lighter than a linear supply because the transformer can be much smaller.
