1Active dynamic filtering — Active dynamic filtering, ADF, is a three phase power electronics based power flow control technology that can effectively be used to isolate and remove electrical behaviours that cause excess losses and disruptions in the electrical… …
2Power supply unit (computer) — Power supply unit with top cover removed A power supply unit (PSU) supplies direct current (DC) power to the other components in a computer. It converts general purpose alternating current (AC) electric power from the mains (110 V to… …
3Power factor — For other uses, see Power factor (pistol). The power factor of an AC electric power system is defined as the ratio of the real power flowing to the load over the apparent power in the circuit,[1][2] and is a dimensionless number between 0 and 1… …
4Power conditioner — A power conditioner (also known as a line conditioner or power line conditioner) is a device intended to improve the “quality” of the power (see power quality) that is delivered to electrical load equipment. While there is no official definition… …
5Power line communication — or power line carrier (PLC), also known as power line digital subscriber line (PDSL), mains communication, power line telecom (PLT), power line networking (PLN), or broadband over power lines (BPL) are systems for carrying data on a conductor… …
6Filter design — is the process of designing a filter (in the sense in which the term is used in signal processing, statistics, and applied mathematics), often a linear shift invariant filter, which satisfies a set of requirements, some of which are contradictory …
7Active pixel sensor — An active pixel sensor (APS) is an image sensor consisting of an integrated circuit containing an array of pixel sensors, each pixel containing a photodetector and an active amplifier. There are many types of active pixel sensors including the… …
8Power supply — For the Budgie album, see Power Supply (album). A vacuum tube rackmount adjustable power supply, capable of +/ 1500 volts DC, 0 to 100mA output, with amperage limiting capability. A power supply is a device that supplies electrical energy …
9Active SETI — A representation of the 1679 bit Arecibo message. Active SETI (Active Search for Extra Terrestrial Intelligence) is the attempt to send messages to intelligent aliens. Active SETI messages are usually in the form of radio signals. Physical… …
