Specific power — In engineering, the term specific power can refer to power either per unit of mass, volume or area, although power per unit of volume is more formally known as power density, and power per unit area as surface power density. [… … Wikipedia
Surface plasmon — Surface plasmons, also referred to in the literature as surface plasma polaritons, are fluctuations in the electron density at the boundary of two materials. Plasmons are the collective vibrations of an electron gas (or plasma) surrounding the… … Wikipedia
Power semiconductor device — Power semiconductor devices are semiconductor devices used as switches or rectifiers in power electronic circuits (switch mode power supplies for example). They are also called power devices or when used in integrated circuits, called power… … Wikipedia
Power MOSFET — A Power MOSFET is a specific type of Metal Oxide Semiconductor Field Effect Transistor (MOSFET) designed to handle large power. Compared to the other power semiconductor devices (IGBT, Thyristor...), its main advantages are high commutation speed … Wikipedia
Power electronic substrate — The role of the substrate in power electronics is to provide the interconnections to form an electric circuit (like a printed circuit board), and to cool the components. Compared to materials and techniques used in lower power microelectronics,… … Wikipedia
Surface wave — Diving grebe creates surface waves In physics, a surface wave is a mechanical wave that propagates along the interface between differing media, usually two fluids with different densities. A surface wave can also be an electromagnetic wave guided … Wikipedia
Fusion power — The Sun is a natural fusion reactor. Fusion power is the power generated by nuclear fusion processes. In fusion reactions two light atomic nuclei fuse together to form a heavier nucleus (in contrast with fission power). In doing so they release a … Wikipedia
Wind profile power law — The wind profile power law is a relationship between the wind speeds at one height, and those at another. The power law is often used in wind power assessments [Elliott, D.L., C.G. Holladay, W.R. Barchet, H.P. Foote, and W.F. Sandusky, 1986,… … Wikipedia
