Benefits of IGBT Technology versus SCR Dimming

... Since IGBT dimmers are lightweight at less than 2 pounds per dimmer, more efficient at any load, create no mechanical buzz or hum, and use natural-convection cooling to produce less heat, they can be distributed adjacent to the required dimmed load. Distributed Dimming is the most cost effective way ...

Series and Parallel Resistors

... Circuits are often composed of multiple resistors connected in various ways. Two general configurations that recur again and again are the so-called “series” and “parallel” combinations. Many resistor networks can be broken down into these simple units. For the sake of the following discussion, assu ...

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.
