  2. Electric power conversion - Wikipedia

    en.wikipedia.org/wiki/Electric_power_conversion

    In electrical engineering, power conversion is the process of converting electric energy from one form to another. 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 can include simpler ...

  3. Power electronics - Wikipedia

    en.wikipedia.org/wiki/Power_electronics

    A PCs power supply is an example of a piece of power electronics, whether inside or outside of the cabinet. Power electronics is the application of electronics to the control and conversion of electric power. The first high-power electronic devices were made using mercury-arc valves. In modern systems, the conversion is performed with ...

  4. Power supply - Wikipedia

    en.wikipedia.org/wiki/Power_supply

    A power supply is an electrical device that supplies electric power to an electrical load. The main purpose of a power supply is to convert electric current from a source to the correct voltage, current, and frequency to power the load. As a result, power supplies are sometimes referred to as electric power converters.

  5. Signal processing - Wikipedia

    en.wikipedia.org/wiki/Signal_processing

    Signal processing is an electrical engineering subfield that focuses on analyzing, modifying and synthesizing signals, such as sound, images, potential fields, seismic signals, altimetry processing, and scientific measurements. [ 1 ] Signal processing techniques are used to optimize transmissions, digital storage efficiency, correcting ...

  6. Power inverter - Wikipedia

    en.wikipedia.org/wiki/Power_inverter

    A power inverter, inverter, or invertor is a power electronic device or circuitry that changes direct current (DC) to alternating current (AC). [1] The resulting AC frequency obtained depends on the particular device employed. Inverters do the opposite of rectifiers which were originally large electromechanical devices converting AC to DC.

  7. Voltage converter - Wikipedia

    en.wikipedia.org/wiki/Voltage_converter

    A common use of the voltage converter is for a device that allows appliances made for the mains voltage of one geographical region to operate in an area with different voltage. Such a device may be called a voltage converter, power converter, travel adapter, etc. Most single phase alternating-current electrical outlets in the world supply power ...

  8. Electronics - Wikipedia

    en.wikipedia.org/wiki/Electronics

    Electronics is a scientific and engineering discipline that studies and applies the principles of physics to design, create, and operate devices that manipulate electrons and other electrically charged particles. Electronics is a subfield of physics [1][2] and electrical engineering which uses active devices such as transistors, diodes, and ...

  9. DC-to-DC converter - Wikipedia

    en.wikipedia.org/wiki/DC-to-DC_converter

    Power engineering. A DC-to-DC converter is an electronic circuit or electromechanical device that converts a source of direct current (DC) from one voltage level to another. It is a type of electric power converter. Power levels range from very low (small batteries) to very high (high-voltage power transmission).
