Phase fired controllers — Phase control (PFC), also called phase cutting, is a method of pulse width modulation (PWM) for power limiting, applied to AC voltages. It works by modulating a thyristor, SCR, triac, thyratron, or other such gated diode like devices into and out … Wikipedia
Transformer types — Circuit symbols Transformer with two windings and iron core. Step down or step up transformer. The symbol shows which winding has more turns, but not usually the … Wikipedia
Phase converter — A phase converter is a device that converts power provided as single or multiple phases to a different number of phases.The majority of phase converters are used to produce three phase electrical power from a single phase source, thus allowing… … Wikipedia
Phase inversion — A phase inversion is the introduction of a phase difference of 180° into a waveform. As such, it is more properly called a polarity inversion, as phase can differ relative to frequency but polarity is absolute.For example, in a push pull power… … Wikipedia
Three-phase electric power — This article deals with where, how and why three phase is used. For information on the basic mathematics and principles of three phase, see three phase. Three phase electric power is a common method of alternating current electric power… … Wikipedia
Distribution transformer — Single phase distribution transformer in Canada A distribution transformer is a transformer that provides the final voltage transformation in the electric power distribution system, stepping down the voltage used in the distribution lines to the… … Wikipedia
Delta-wye transformer — Not to be confused with Y Δ transform. A delta wye (Δ Y) transformer is a transformer that converts three phase electric power without a neutral wire into 3 phase power with a neutral wire. It can be a single three phase transformer, or built… … Wikipedia
Single-phase electric power — In electrical engineering, single phase electric power refers to the distribution of alternating current electric power using a system in which all the voltages of the supply vary in unison. Single phase distribution is used when loads are mostly … Wikipedia
