  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.

  3. Voltage converter - Wikipedia

    en.wikipedia.org/wiki/Voltage_converter

    A voltage converter is an electric power converter which changes the voltage of an electrical power source. It may be combined with other components to create a power supply . AC and DC

  4. DC-to-DC converter - Wikipedia

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

    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).

    Energy transformation, also known as energy conversion, ... The most efficient gas-fired electrical power stations can achieve 50% conversion efficiency.

  7. High-voltage direct current - Wikipedia

    en.wikipedia.org/wiki/High-voltage_direct_current

    Long distance HVDC lines carrying hydroelectricity from Canada's Nelson River to this converter station where it is converted to AC for use in southern Manitoba's grid. A high-voltage direct current (HVDC) electric power transmission system uses direct current (DC) for electric power transmission, in contrast with the more common alternating current (AC) transmission systems.

  8. Energy conversion efficiency - Wikipedia

    en.wikipedia.org/wiki/Energy_conversion_efficiency

    Efficiency of power plants, world total, 2008. Energy conversion efficiency (η) is the ratio between the useful output of an energy conversion machine and the input, in energy terms. The input, as well as the useful output may be chemical, electric power, mechanical work, light (radiation), or heat.

  9. Direct energy conversion - Wikipedia

    en.wikipedia.org/wiki/Direct_energy_conversion

    Direct energy conversion (DEC) or simply direct conversion converts a charged particle's kinetic energy into a voltage. It is a scheme for power extraction from nuclear fusion . A basic direct converter
