  2. Rectifier - Wikipedia

    en.wikipedia.org/wiki/Rectifier

    A variety of silicon diodes of different current ratings. At left is a bridge rectifier. On the 3 center diodes, a painted band identifies the cathode terminal. Silicon diodes are the most widely used rectifiers for lower voltages and powers, and have largely replaced other rectifiers. Due to their substantially lower forward voltage (0.3V ...

    Various semiconductor diodes. Left: A four-diode bridge rectifier.Next to it is a 1N4148 signal diode.On the far right is a Zener diode.In most diodes, a white or black painted band identifies the cathode into which electrons will flow when the diode is conducting.

  5. Selenium rectifier - Wikipedia

    en.wikipedia.org/wiki/Selenium_rectifier

    A selenium rectifier is about the same size as a copper-oxide rectifier, but is much larger than a silicon or germanium diode. Selenium rectifiers have a long but not indefinite service life of 60,000 to 100,000 hours, depending on rating and cooling. The rectifier can show some unforming of the rectifier characteristic after long storage. [6]

  6. 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 .

  7. Diode bridge - Wikipedia

    en.wikipedia.org/wiki/Diode_bridge

    A hand-made diode bridge. The silver band on the diodes indicates the cathode side of the diode.. A diode bridge is a bridge rectifier circuit of four diodes that is used in the process of converting alternating current (AC) from the input terminals to direct current (DC, i.e. fixed polarity) on the output terminals.
