... As just described, the energy-harnessing power supply must have a wide input-voltage range, be able to operate on a very small amount of input power, and avoid start-up oscillations when powered from current-limited sources. TI’s TPS62125 is such a power supply, because it operates from a 3- to 17-V ...

Three-phase electric power



Three-phase electric power is a common method of alternating-current electric power generation, transmission, and distribution. It is a type of polyphase system and is the most common method used by electrical grids worldwide to transfer power. It is also used to power large motors and other heavy loads. A three-phase system is usually more economical than an equivalent single-phase or two-phase system at the same line to ground voltage because it uses less conductor material to transmit electrical power.The three-phase system was independently invented by Galileo Ferraris, Mikhail Dolivo-Dobrovolsky, Jonas Wenström and Nikola Tesla in the late 1880s.
