51Impedance matching — In electronics, impedance matching is the practice of designing the input impedance of an electrical load (or the output impedance of its corresponding signal source) to maximize the power transfer and/or minimize reflections from the load.… …
52Wireless energy transfer — or wireless power is the transmission of electrical energy from a power source to an electrical load without artificial interconnecting conductors. Wireless transmission is useful in cases where interconnecting wires are inconvenient, hazardous,… …
53Brushed DC electric motor — A brushed DC motor is an internally commutated electric motor designed to be run from a direct current power source. Contents 1 Simple two pole DC motor 2 The commutating plane 2.1 Compensation for stator field distortion …
54Transformer 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 …
55Distribution 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… …
56Thyristor — The thyristor is a solid state semiconductor device with four layers of alternating N and P type material. They act as bistable switches, conducting when their gate receives a current pulse, and continue to conduct for as long as they are forward …
57steel — steellike, adj. /steel/, n. 1. any of various modified forms of iron, artificially produced, having a carbon content less than that of pig iron and more than that of wrought iron, and having qualities of hardness, elasticity, and strength varying …
58Linear regulator — In electronics, a linear regulator is a voltage regulator based on an active device (such as a bipolar junction transistor, field effect transistor or vacuum tube) operating in its linear region (in contrast, a switching regulator is based on a… …
59Grid energy storage — is used to manage the flow of electrical energy. For large scale load levelling on an interconnected electrical system, electric energy producers send low value off peak excess electricity over the electricity transmission grid to temporary… …
