... COUT, which enables VOUT to rise. VOUT is regulated to within 5% of 12V by an oscillator pulse gating scheme that turns the charge pump on and off based on the comparator results of VOUT and a reference voltage. First, a resistor divider senses VOUT; if the output of the divider (VDIV) is less than ...

... 3. The 1N4007 diode is the best all-around choice for replacement of selenium rectifiers found in radios, test equipment, and TV sets. The price is so low, under 10 cents, that it doesn't pay to use anything less. The 1N5408 is another choice, though really overkill in most cases. 4. I continue to r ...

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.
