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 ...

3. Diode bridge - Wikipedia

   en.wikipedia.org/wiki/Diode_bridge

   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. Its function is to convert the negative voltage portions of the AC waveform to positive voltage, after which a low-pass ...

4. Diode - Wikipedia

   en.wikipedia.org/wiki/Diode

   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. Bridge circuit - Wikipedia

   en.wikipedia.org/wiki/Bridge_circuit

   In power supply design, a bridge circuit or bridge rectifier is an arrangement of diodes or similar devices used to rectify an electric current, i.e. to convert it from an unknown or alternating polarity to a direct current of known polarity. In some motor controllers, an H-bridge is used to control the direction the motor turns.

6. Schottky diode - Wikipedia

   en.wikipedia.org/wiki/Schottky_diode

   anode and cathode. Electronic symbol. The Schottky diode (named after the German physicist Walter H. Schottky ), also known as Schottky barrier diode or hot-carrier diode, is a semiconductor diode formed by the junction of a semiconductor with a metal. It has a low forward voltage drop and a very fast switching action.

7. p–n diode - Wikipedia

   en.wikipedia.org/wiki/P–n_diode

   Nonideal p–n diode current-voltage characteristics. The ideal diode has zero resistance for the forward bias polarity, and infinite resistance (conducts zero current) for the reverse voltage polarity; if connected in an alternating current circuit, the semiconductor diode acts as an electrical rectifier. The semiconductor diode is not ideal.
