  2. Voltage converter - Wikipedia

    en.wikipedia.org/wiki/Voltage_converter

    AC voltage conversion uses a transformer. Conversion from one DC voltage to another requires electronic circuitry (electromechanical equipment was required before the development of semiconductor electronics), like a DC-DC converter. [1] Mains power (called household current in the US) is universally AC. [2]

  3. Electronic symbol - Wikipedia

    en.wikipedia.org/wiki/Electronic_symbol

    Wire crossover symbols for circuit diagrams. The CAD symbol for insulated crossing wires is the same as the older, non-CAD symbol for non-insulated crossing wires. To avoid confusion, the wire "jump" (semi-circle) symbol for insulated wires in non-CAD schematics is recommended (as opposed to using the CAD-style symbol for no connection), so as to avoid confusion with the original, older style ...

  4. Reference designator - Wikipedia

    en.wikipedia.org/wiki/Reference_designator

    voltage regulators are often "U" for IC, pots and trimmers often "R" for resistor X: Socket connector for another item not P or J, paired with the letter symbol for that item (XV for vacuum tube socket, XF for fuse holder, XA for printed circuit assembly connector, XU for integrated circuit connector, XDS for light socket, etc.) X, XTAL, Y

  5. Electrical drawing - Wikipedia

    en.wikipedia.org/wiki/Electrical_drawing

    An electrical drawing is a type of technical drawing that shows information about power, lighting, and communication for an engineering or architectural project.Any electrical working drawing consists of "lines, symbols, dimensions, and notations to accurately convey an engineering's design to the workers, who install the electrical system on the job".

  6. Electric power conversion - Wikipedia

    en.wikipedia.org/wiki/Electric_power_conversion

    In North America and northern South America, it is usually 120 volts, 60 hertz (Hz), but in Europe, Asia, Africa, and many other parts of the world, it is usually 230 volts, 50 Hz. [2] Aircraft often use 400 Hz power internally, so 50 Hz or 60 Hz to 400 Hz frequency conversion is needed for use in the ground power unit used to power the ...

  7. IC power-supply pin - Wikipedia

    en.wikipedia.org/wiki/IC_power-supply_pin

    More advanced circuits often have pins carrying voltage levels for more specialized functions, and these are generally labeled with some abbreviation of their purpose. For example, V USB for the supply delivered to a USB device (nominally 5 V), V BAT for a battery, or V ref for the reference voltage for an analog-to-digital converter. Systems ...

  8. Electric power - Wikipedia

    en.wikipedia.org/wiki/Electric_power

    Electric power is the rate of transfer of electrical energy within a circuit.Its SI unit is the watt, the general unit of power, defined as one joule per second.Standard prefixes apply to watts as with other SI units: thousands, millions and billions of watts are called kilowatts, megawatts and gigawatts respectively.

    A type of voltage converter that stores energy in an inductor. flyback transformer A type of transformer that recovers energy stored in its own core. Historically used in the deflection circuits of CRT display systems. forward converter A type of voltage converter that relies on transformer action to couple energy to its output circuit.
