WebThyristor ist die Bezeichnung für ein Bauteil in der Elektrotechnik.Es ist ein Kofferwort aus den beiden Bezeichnungen Thyratron und Transistor.. Ein Thyristor ist ein Halbleiterbauelement, das aus vier oder mehr Halbleiterschichten wechselnder Dotierung aufgebaut ist. Thyristoren sind einschaltbare Bauelemente, das heißt, sie sind im …

WebEen thyristor is een halfgeleider, met de werking van een elektronische schakelaar, die geschikt is om grote vermogens bij hoge spanningen met betrekkelijk weinig verlies te schakelen.. Werking. Een thyristor gedraagt zich als een schakelbare diode, die met een extra stuuraansluiting (de z.g. gate), te bedienen is.De kathode wordt gemeenschappelijk …

WebUn thyristor est un interrupteur électronique semi-conducteur à l'état solide constitué de quatre couches, alternativement dopées N et P. C'est un des composants essentiels de l'électronique de puissance.Il tire son nom du grec thura qui signifie porte et du suffixe « istor » qui provient du mot transistor.Il se comporte comme une bascule synchrone, c'est-à …

WebThe thyristor is a solid-state semiconductor device similar to the diode, but with an extra control terminal that is used to switch the device on at a defined instant. Because thyristors have breakdown voltages of only a few kilovolts each, HVDC thyristor valves are built using large numbers of thyristors connected in series.

WebThe integrated gate-commutated thyristor (IGCT) is a power semiconductor electronic device, used for switching electric current in industrial equipment. It is related to the gate turn-off (GTO) thyristor.. It was jointly developed by Mitsubishi and ABB. Like the GTO thyristor, the IGCT is a fully controllable power switch, meaning that it can be turned …

WebA thyristor (/ θ aɪ ˈ r ɪ s t ər /) is a solid-state semiconductor device with four layers of alternating P-and N-type materials used for high-power applications.: 12 It acts exclusively as a bistable switch (or a latch),: 12 conducting when the gate receives a current trigger, and continuing to conduct until the voltage across the device is reversed biased, or until the …

WebA crowbar circuit is an electrical circuit used for preventing an overvoltage or surge condition of a power supply unit from damaging the circuits attached to the power supply. It operates by putting a short circuit or low resistance path across the voltage output (V o), like dropping a crowbar across the output terminals of the power supply. Crowbar circuits are …

WebA surge protector (or spike suppressor, surge suppressor, surge diverter, surge protection device (SPD) or transient voltage surge suppressor (TVSS) is an appliance or device intended to protect electrical devices from voltage spikes in alternating current (AC) circuits. A voltage spike is a transient event, typically lasting 1 to 30 microseconds, that may reach …

WebA simple RC snubber uses a small resistor (R) in series with a small capacitor (C). 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 ( /) across the thyristor to a value which will not trigger it.An appropriately designed RC …

WebLe triac (de l'anglais triode for alternating current) est un composant électronique équivalent à la mise en parallèle de deux thyristors montés tête-bêche (l'anode de l'un serait reliée à la cathode de l'autre, les gâchettes respectives étant commandées simultanément).
