An introduction to AC/DC power supply as a simple system

... The input is the 120 volt 60 Hz AC power line. Alternately, the input may be 240 volt AC. The power supply converts the AC into DC and provides one or more DC output voltages. Some modern electronic circuits need two or more different voltages. Common voltages are 48, 24, 15, 12, 9, 5, 3.3, 2.5, 1.8 ...

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.
