  2. Inverter compressor - Wikipedia

    en.wikipedia.org/wiki/Inverter_compressor

    In air conditioning, an inverter compressor is a compressor that is operated with an inverter. In the hermetic type, it can either be a scroll or reciprocating compressor . This type of compressor uses a drive to control the compressor motor speed to modulate cooling capacity.

  3. Arc welding - Wikipedia

    en.wikipedia.org/wiki/Arc_welding

    Arc welding power supplies can deliver either direct (DC) or alternating (AC) current to the work, while consumable or non-consumable electrodes are used. The welding area is usually protected by some type of shielding gas (e.g. an inert gas), vapor, or slag. Arc welding processes may be manual, semi-automatic, or fully automated.

  4. Welding power supply - Wikipedia

    en.wikipedia.org/wiki/Welding_power_supply

    The high frequency inverter-based welding machines are typically more efficient and provide better control of variable functional parameters than non-inverter welding machines. The IGBTs in an inverter based machine are controlled by a microcontroller, so the electrical characteristics of the welding power can be changed by software in real ...

  5. War of the currents - Wikipedia

    en.wikipedia.org/wiki/War_of_the_currents

    The war of the currents was a series of events surrounding the introduction of competing electric power transmission systems in the late 1880s and early 1890s. It grew out of two lighting systems developed in the late 1870s and early 1880s; arc lamp street lighting running on high-voltage alternating current (AC), and large-scale low-voltage direct current (DC) indoor incandescent lighting ...

  6. Skin effect - Wikipedia

    en.wikipedia.org/wiki/Skin_effect

    The internal component of a round wire's inductance vs. the ratio of skin depth to radius. That component of the self inductance is reduced below μ/8 π as skin depth becomes small (as frequency increases). The ratio AC resistance to DC resistance of a round wire versus the ratio of the wire's radius to the skin depth.

  7. Alternating current - Wikipedia

    en.wikipedia.org/wiki/Alternating_current

    The abbreviations AC and DC are often used to mean simply alternating and direct, respectively, as when they modify current or voltage. [ 1 ] [ 2 ] The usual waveform of alternating current in most electric power circuits is a sine wave , whose positive half-period corresponds with positive direction of the current and vice versa (the full ...

  8. Universal motor - Wikipedia

    en.wikipedia.org/wiki/Universal_motor

    [4] [note 1] If an ordinary series-wound DC motor were connected to an AC supply, it would run very poorly. The universal motor is modified in several ways to allow for proper AC supply operation. There is a compensating winding typically added, along with laminated pole pieces, as opposed to the solid pole pieces found in DC motors. [2]

  9. Electric power conversion - Wikipedia

    en.wikipedia.org/wiki/Electric_power_conversion

    A power converter is an electrical device for converting electrical energy between alternating current (AC) and direct current (DC). It can also change the voltage or frequency of the current. Power converters include simple devices such as transformers , and more complex ones like resonant converters .
