  2. Thyristor - Wikipedia

    en.wikipedia.org/wiki/Thyristor

    A thyristor (/ θaɪˈrɪstər /) is a solid-state semiconductor device which can be thought of as being a highly robust and switchable diode, allowing the passage of current in one direction but not the other, often under control of a gate electrode, that is used in high power applications like inverters and radar generators.

  3. Reliance of the Traveller - Wikipedia

    OCLC. 780082934. Umdat as-Salik wa 'Uddat an-Nasik (Reliance of the Traveller and Tools of the Worshipper, also commonly known by its shorter title Reliance of the Traveller) [1][2] is a classical manual of fiqh for the Shafi'i school of Islamic jurisprudence. The author of the main text is 14th-century scholar Shihabuddin Abu al-'Abbas Ahmad ...

  4. Voltage controller - Wikipedia

    en.wikipedia.org/wiki/Voltage_controller

    A Voltage controller thyristor based dimmer rack An electrical schematic for a typical SCR-based light dimmer. A voltage controller, also called an AC voltage controller or AC regulator is an electronic module based on either thyristors, triodes for alternating current, silicon-controlled rectifiers or insulated-gate bipolar transistors, which converts a fixed voltage, fixed frequency ...

  5. TRIAC - Wikipedia

    en.wikipedia.org/wiki/TRIAC

    TRIAC. For other uses, see Triac. A TRIAC (triode for alternating current; also bidirectional triode thyristor or bilateral triode thyristor[ 1 ]) is a three-terminal electronic component that conducts current in either direction when triggered. The term TRIAC is a genericised trademark. TRIACs are a subset of thyristors (analogous to a relay ...

  6. Thyratron - Wikipedia

    en.wikipedia.org/wiki/Thyratron

    A thyratron is a type of gas-filled tube used as a high-power electrical switch and controlled rectifier. Thyratrons can handle much greater currents than similar hard-vacuum tubes. Electron multiplication occurs when the gas becomes ionized, producing a phenomenon known as a Townsend discharge. Gases used include mercury vapor, xenon, neon ...

  7. Static synchronous compensator - Wikipedia

    en.wikipedia.org/wiki/Static_synchronous_compensator

    Static synchronous compensator. In Electrical Engineering , a static synchronous compensator (STATCOM) is a shunt-connected, reactive compensation device used on transmission networks. It uses power electronics to form a voltage-source converter that can act as either a source or sink of reactive AC power to an electricity network.

  8. Silicon controlled rectifier - Wikipedia

    en.wikipedia.org/wiki/Silicon_controlled_rectifier

    A silicon controlled rectifier or semiconductor controlled rectifier is a four-layer solid-state current -controlling device. The name "silicon controlled rectifier" is General Electric 's trade name for a type of thyristor. The principle of four-layer p–n–p–n switching was developed by Moll, Tanenbaum, Goldey, and Holonyak of Bell ...

  9. HVDC converter - Wikipedia

    en.wikipedia.org/wiki/HVDC_converter

    A twelve-pulse thyristor converter for Pole 2 of the HVDC Inter-Island between the North and South Islands of New Zealand. The person at the bottom gives an idea of scale. Each thyristor valve will typically contain tens or hundreds of thyristor levels, each operating at a different (high) potential with respect to earth. [16]
