What else can I help you with?
What are the three terminals of a silicon bilateral switch?
Anode, Cathode and Gate. Like in a SCR
Why gate is closer to cathode in scr?
A: To partially eliminate the problems with cathode current hugging
What is unidirectional sampling gate?
which has only one polarity....
Why thyristor is called latching device?
once the gate has triggered conduction between cathode and anode, the gate has no further control; conduction will continue until power is removed from the cathode to anode circuit.
Why does SCR turn ON by gate current?
to make the revers biased p-n junction in SCR to be conducting.when we apply gate signal across gate and cathode it establish conducting part,thus the current from anode to cathode flow i.e main current.even after we remove the gate signal SCR in conducting mode because now this conducting path is maintain by main current i.e current from anode to cathode
How is an SCR turned on?
A: An scr is a 4 layer diode and has 3 terminals gate anode and cathode. To turn it on the gate must be positive with respect to the cathode and have enough voltage and current to turn it on. The turn on also depends on the load. Another possibility is to increase the potential cathode to anode until it will turn on but this mode is not predictable. Once on there only two way to shut it off. Remove to load below the holding current or momentarily reverse the voltage
What is happening to the voltage value of scr if its gate is triggered?
the anode-cathode voltage drops
How can an SCR be made to conduct?
An SCR has three legs. The anode, cathode, and gate. The control voltage sent to the gate will allow the SCR to conduct.
What are the two conditions necessary for a thyristor to begin to conduct?
There are more than two conditions that can make a thyristor conduct, but the general (functional) ones are: 1) positive voltage form anode to cathode, and 2) a positive voltage on the trigger input (referenced to the cathode) for a standard polarity thyristor. Other conditions can be: A) Anode-Cathode Voltage exceeding thyristor witholding voltage. B) Overtemperature of the thyristor chip C) Faulty thyristor (can be caused by overloads)
How do you work thyristor?
The thyristor functions in such a way that when the anode voltage is greater than the cathode voltage , it is not triggered but only triggers when a gate signal is applied at the gate of the device.
What is the symbol for a thyristor?
It is a standard diode, with an additional line leaving the cathode (- side) for the gate. See wikipedia link.
What do you do if you forgot to throw the switch in the dungeon?
you wont open the gate from mordens gate to the dungon.
