  2. Active rectification - Wikipedia

    en.wikipedia.org/wiki/Active_rectification

    Active full-wave rectification with two MOSFETs and a center tap transformer. Replacing a diode with an actively controlled switching element such as a MOSFET is the heart of active rectification. MOSFETs have a constant very low resistance when conducting, known as on-resistance (R DS(on)). They can be made with an on-resistance as low as 10 ...

    Later he gives a corresponding equation for current as a function of voltage under additional assumptions, which is the equation we call the Shockley ideal diode equation. [3] He calls it "a theoretical rectification formula giving the maximum rectification", with a footnote referencing a paper by Carl Wagner , Physikalische Zeitschrift 32 , pp ...

  4. Diode modelling - Wikipedia

    en.wikipedia.org/wiki/Diode_modelling

    Ideal diode with a series voltage source and resistor. The I-V characteristic of the final circuit looks like this: I-V characteristic of an ideal diode with a series voltage source and resistor. The real diode now can be replaced with the combined ideal diode, voltage source and resistor and the circuit then is modelled using just linear elements.

  5. p–n junction - Wikipedia

    en.wikipedia.org/wiki/P–n_junction

    Zener diodes have a low breakdown voltage. A standard value for breakdown voltage is for instance 5.6 V. This means that the voltage at the cathode cannot be more than about 5.6 V higher than the voltage at the anode (though there is a slight rise with current), because the diode breaks down, and therefore conducts, if the voltage gets any higher.

  6. p–n diode - Wikipedia

    en.wikipedia.org/wiki/P–n_diode

    The semiconductor diode is not ideal. As shown in the figure, the diode does not conduct appreciably until a nonzero knee voltage (or turn-on, cut-in, or threshold voltage) is reached, whose value depends on the semiconductor (listed in Diode § Forward threshold voltage for various semiconductors). Above this voltage the slope of the current ...

  8. Semiconductor device - Wikipedia

    en.wikipedia.org/wiki/Semiconductor_device

    A semiconductor diode is a device typically made from a single p–n junction.At the junction of a p-type and an n-type semiconductor, there forms a depletion region where current conduction is inhibited by the lack of mobile charge carriers.
