  2. Universal Power Adapter for Mobile Devices - Wikipedia

    en.wikipedia.org/wiki/Universal_Power_Adapter...

    The power supply was required to have an output capacitive energy of less than 15.1 µJ and an inductive energy at disconnect of less than 5.3 µJ. [ 1 ] The standard defines an AC adapter to power devices requiring from 10 W to 130 W (~20 V × 6.5 A) or (extended voltage option) up to 240 W (60 V × 4 A). [ 2 ]

    The first Power Delivery specification (Rev. 1.0) defined six fixed power profiles for the power sources. PD-aware devices implement a flexible power management scheme by interfacing with the power source through a bidirectional data channel and requesting a certain level of electrical power, variable up to 5 A and 20 V depending on supported ...

  4. Backside power delivery - Wikipedia

    en.wikipedia.org/wiki/Backside_Power_Delivery

    By moving the power delivery network to the backside, BPD reduces the voltage droop experienced by transistors. This is because the power interconnects can be made larger and less resistive, providing a more stable power supply. This stability allows transistors to operate at higher frequencies with less risk of performance degradation. [1]

  5. Uninterruptible power supply - Wikipedia

    en.wikipedia.org/wiki/Uninterruptible_power_supply

    Classic solutions such as passive filters reduce THD I to 5%–10% at full load. They are reliable, but big and only work at full load, and present their own problems when used in tandem with generators. An alternative solution is an active filter. Through the use of such a device, THD I can drop to 5% over the full power range. The newest ...

  6. Power-system automation - Wikipedia

    en.wikipedia.org/wiki/Power-system_automation

    Monitoring and control of power delivery systems in the substation and on the pole reduce the occurrence of outages and shorten the duration of outages that do occur. The IEDs, communications protocols, and communications methods, work together as a system to perform power-system automation. The term “power system” describes the collection ...

  7. Power distribution unit - Wikipedia

    en.wikipedia.org/wiki/Power_distribution_unit

    Data centers face challenges in power protection and management solutions. This is why many data centers rely on PDU monitoring to improve efficiency, uptime, and growth. [2] [3] For data center applications, the power requirement is typically much larger than a home or office style power strips with power inputs as large as 22 kVA or even ...

  8. Diesel rotary uninterruptible power supply - Wikipedia

    en.wikipedia.org/wiki/Diesel_rotary...

    Most forms of uninterruptible power supply (UPS) can be either powered by battery or flywheel energy. These are ready for immediate use at the instant that the mains electricity fails, but the relatively small and finite amount of stored energy they contain makes them suitable for short periods of use, typically in the order of a few dozen minutes to a couple of hours depending on the actual load.
