  2. Transformer types - Wikipedia

    en.wikipedia.org/wiki/Transformer_types

    A planar transformer Exploded view: the spiral primary "winding" on one side of the PCB (the spiral secondary "winding" is on the other side of the PCB) Manufacturers either use flat copper sheets or etch spiral patterns on a printed circuit board to form the "windings" of a planar transformer, replacing the turns of wire used to make other ...

    en.wikipedia.org/wiki/British_Rail_Class_93_(St...

    The Class 93 locomotive is a derivative of the Class 88 electro-diesel and Class 68 diesel locomotives, both of which were built by Stadler. [ 7 ] [ 13 ] As with Class 88 locomotives, Class 93s are designed as fast freight locomotives that use electric power while under the wires, but that are also capable of self-powered operations. [ 7 ]

    en.wikipedia.org/wiki/List_of_automotive_light...

    Bulbs used for headlamps, turn signals and brake lamps may be required to comply with international and national regulations governing the types of lamps used. Other automotive lighting applications such as auxiliary lamps or interior lighting may not be regulated, but common types are used by many automotive manufacturers.

  5. Solid-state transformer - Wikipedia

    en.wikipedia.org/wiki/Solid-state_transformer

    This transformer is smaller due to smaller DC-DC inverting stages between transformer coils, which consequently mean smaller transformer coils required to step up or step down voltages. A solid-state transformer can actively regulate voltage and current. Some can convert single-phase power to three-phase power and vice versa.

  6. Psychophysiology - Wikipedia

    en.wikipedia.org/wiki/Psychophysiology

    Psychophysiology measures exist in multiple domains; reports, electrophysiological studies, studies in neurochemistry, neuroimaging and behavioral methods. [5] Evaluative reports involve participant introspection and self-ratings of internal psychological states or physiological sensations, such as self-report of arousal levels on the self-assessment manikin, [6] or measures of interoceptive ...

    en.wikipedia.org/wiki/History_of_the_Tesla_coil

    [33] [12] [91] [84] [92] [93] A grounded spark-excited capacitor-tuned Tesla transformer attached to an elevated wire antenna transmitted radio waves, which were received across the room by a wire antenna attached to a receiver consisting of a second grounded resonant transformer tuned to the transmitter's frequency, which lighted a Geissler tube.

  8. Scott-T transformer - Wikipedia

    en.wikipedia.org/wiki/Scott-T_transformer

    Standard Scott Connection 3 φ to 2 φ. Assuming the desired voltage is the same on the two and three phase sides, the Scott-T transformer connection (shown right) consists of a centre-tapped 1:1 ratio main transformer, T1, and a √ 3 /2(≈86.6%) ratio teaser transformer, T2. The centre-tapped side of T1 is connected between two of the phases ...

  9. Amorphous metal transformer - Wikipedia

    en.wikipedia.org/wiki/Amorphous_metal_transformer

    An amorphous metal transformer (AMT) is a type of energy efficient transformer found on electric grids. [1] The magnetic core of this transformer is made with a ferromagnetic amorphous metal. The typical material is an alloy of iron with boron, silicon, and phosphorus in the form of thin (e.g. 25 μm) foils rapidly cooled from melt.
