  2. Snubber - Wikipedia

    en.wikipedia.org/wiki/Snubber

    A simple RC snubber uses a small resistor (R) in series with a small capacitor (C). [1] This combination can be used to suppress the rapid rise in voltage across a thyristor , preventing the erroneous turn-on of the thyristor; it does this by limiting the rate of rise in voltage ( d V / d t {\displaystyle dV/dt} ) across the thyristor to a ...

    en.wikipedia.org/wiki/Gate_turn-off_thyristor

    Substantial snubber circuits are added around the device to limit the rise of voltage at turn off. Resetting the snubber circuit usually places a minimum on-time requirement on GTO-based circuits. The minimum on- and off-time is handled in DC motor chopper circuits by using a variable switching frequency at the lowest and highest duty cycle.

    en.wikipedia.org/wiki/Power_semiconductor_device

    A snubber circuit is required in order to provide a usable switching curve for this device. Without the snubber circuit, the GTO cannot be used for turning inductive loads off. These devices, because of developments in IGCT technology are not very popular in the power electronics realm.

  5. Thyristor - Wikipedia

    en.wikipedia.org/wiki/Thyristor

    A thyristor (/ θ aɪ ˈ r ɪ s t ər /, from a combination of Greek language θύρα, meaning "door" or "valve", and transistor [1]) 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 ...

  7. Soft-switching three-level inverter - Wikipedia

    en.wikipedia.org/wiki/Soft-switching_three-level...

    This base design is supplemented by a snubber circuit consisting of a few passive components. [5] It prevents the occurrence of simultaneously high values of voltage and current, and hence high power dissipation values, during the switching process. All switching processes therefore take place in a "soft" manner.
