  2. Snubber - Wikipedia

    en.wikipedia.org/wiki/Snubber

    Snubbers allow for free thermal movement of a component during regular conditions, but restrain the component in irregular conditions. [6] A hydraulic snubber allows for pipe deflection under normal operating conditions. When subjected to an impulse load, the snubber becomes activated and acts as a restraint in order to restrict pipe movement. [7]

    A converter connection such that the current through each of the phase terminals of the AC circuit is unidirectional. snubber (circuit) A subcircuit connected to one or more electronic valve devices in order to relieve it (them) of stress as for instance overvoltage transients, switching losses, high rate of rise of current or voltage, etc. [ad]

  4. Gate turn-off thyristor - Wikipedia

    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.

  5. TRIAC - Wikipedia

    en.wikipedia.org/wiki/TRIAC

    When used to control reactive (inductive or capacitive) loads, care must be taken to ensure that the TRIAC turns off correctly at the end of each half-cycle of the AC in the main circuit. TRIACs can be sensitive to fast voltage changes (dv/dt) between MT1 and MT2, so a phase shift between current and voltage caused by reactive loads can lead to ...

  6. 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.
