active power transfer
1Power 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… …
2Power scaling — of a laser is increasing its output power without changing the geometry, shape, or principle of operation. Power scalability is considered an important advantage in a laser design.Usually, power scaling requires a more powerful pump source,… …
3Active solar — technologies are employed to convert solar energy into usable heat, cause air movement for ventilation or cooling, or store heat for future use. Active solar uses electrical or mechanical equipment, such as pumps and fans, to increase the usable… …
4Active measures — (Russian: Активные мероприятия ) were a form of political warfare conducted by the Soviet security services (Cheka, OGPU, NKVD, KGB, and SVR) to influence the course of world events, in addition to collecting intelligence and producing… …
5Power optimization (EDA) — Power optimization refers to the use of electronic design automation tools to optimize (reduce) the power consumption of a digital design, while preserving the functionality.Introduction and historyThe increasing speed and complexity of today’s… …
6Active 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… …
7Wireless energy transfer — or wireless power is the transmission of electrical energy from a power source to an electrical load without artificial interconnecting conductors. Wireless transmission is useful in cases where interconnecting wires are inconvenient, hazardous,… …
8AC power — This article deals with power in AC systems. See Mains electricity for information on utility supplied AC power. Usually hidden from the unaided eye, the blinking of (non incandescent) lighting powered by AC mains is revealed in this motion… …
9Uninterruptible power supply — A small free standing UPS …
10Electric power — is defined as the rate at which electrical energy is transferred by an electric circuit. The SI unit of power is the watt.When electric current flows in a circuit, it can transfer energy to do mechanical or thermodynamic work. Devices convert… …
