  2. 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.

  3. Pre-charge - Wikipedia

    en.wikipedia.org/wiki/Pre-charge

    Pre-charge of the powerline voltages in a high voltage DC application is a preliminary mode which limits the inrush current during the power up procedure. A high-voltage system with a large capacitive load can be exposed to high electric current during initial turn-on.

  4. Power electronics - Wikipedia

    en.wikipedia.org/wiki/Power_electronics

    In contrast to electronic systems concerned with the transmission and processing of signals and data, substantial amounts of electrical energy are processed in power electronics. An AC/DC converter is the most typical power electronics device found in many consumer electronic devices, e.g. television sets, personal computers, battery chargers, etc.

  6. Programmable load - Wikipedia

    en.wikipedia.org/wiki/Programmable_load

    Most commercial DC loads are equipped with microprocessor front end circuits that allow the user to not only program a desired current through the load ('constant current' or CC), but the user can alternatively program the load to have a constant resistance (CR) or constant power dissipation (CP).

  7. Electrical load - Wikipedia

    en.wikipedia.org/wiki/Electrical_load

    An electrical load is an electrical component or portion of a circuit that consumes (active) electric power, [1] [2] such as electrical appliances and lights inside the home. The term may also refer to the power consumed by a circuit. This is opposed to a power supply source, such as a battery or generator, which provides power. [2]

  8. Dummy load - Wikipedia

    en.wikipedia.org/wiki/Dummy_load

    An electronic load (or e-load) is a device or assembly that simulates loading on an electronic circuit. It is used as substitute for a conventional ohmic load resistor. Electronic loads with 800W and 4200W from Höcherl & Hackl. As counterpart to a current source, the electronic load is a current sink. When loading a current source with a fixed ...

  9. HVDC converter - Wikipedia

    en.wikipedia.org/wiki/HVDC_converter

    An HVDC converter converts electric power from high voltage alternating current (AC) to high-voltage direct current (HVDC), or vice versa. HVDC is used as an alternative to AC for transmitting electrical energy over long distances or between AC power systems of different frequencies. [1]
