  2. Shin-Shinano Frequency Converter - Wikipedia

    en.wikipedia.org/wiki/Shin-Shinano_Frequency...

    The 1992 converter uses more conventional air-insulated, water-cooled thyristor valves. In 2008 the original 1977 converter was decommissioned and replaced by a third converter, similar in design to the 1992 converter but using light-triggered thyristors. The Shin-Shinano link operates with a DC link voltage of 125 kV for each converter.

  3. Voltage converter - Wikipedia

    en.wikipedia.org/wiki/Voltage_converter

    A simple voltage dropper can be used to reduce the voltage for low-power devices; if more than 12V is required, or for high-powered devices, a switched-mode power supply is used. The output will usually be DC in the range 1.5–24 V. Power supplies that output either 100–120 V AC or 210–240 V AC are available; they are called inverters ...

  4. 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.

  5. Frequency changer - Wikipedia

    en.wikipedia.org/wiki/Frequency_changer

    Frequency changers are used for converting bulk AC power from one frequency to another, when two adjacent power grids operate at different utility frequency.. A variable-frequency drive (VFD) is a type of frequency changer used for speed control of AC motors such as used for pumps and fans.

  6. Category:Electric power conversion - Wikipedia

    en.wikipedia.org/wiki/Category:Electric_power...

    Articles in this category are about converting electric energy from one impedance, phase or frequency (including direct current) to another.But the energy form remain in the same domain and the focus is on energy conversion – not signal conversion or measurement (like Current-to-voltage converter or Voltage-to-current converter).

  7. Phase converter - Wikipedia

    en.wikipedia.org/wiki/Phase_converter

    An American Rotary Phase Converter with a Transformer. A phase converter is a device that converts electric power provided as single phase to multiple phase or vice versa. The majority of phase converters are used to produce three-phase electric power from a single-phase source, thus allowing the operation of three-phase equipment at a site that only has single-phase electrical service.
