Where does a SCR differ from a power transistor in operation?

thyristor can be scr or triac scr is strictly dc a triac is back to back scr's with a common gate two scr's back to back can be gated independently scrs cost less than triacs an scr can be combined with a full wave bridge to make an equivalent to a triac but this gives an additional 1.5V forward voltage drop

What is forward breakover voltage?

forward-breakover voltage - the voltage at which a device enters the forward-blocking region. The voltage at which the SCR enters the forward-condition region. The value of Vbr(f) is maximum when (Ig=current in gate) Ig=0 and is designate Vbr(f0). When the gate current is increased, Vbr(f) decrease and is designated Vbr(f1), Vbr(f2), and so on, for increasing steps in gate current (Ig1, Ig2, and so on).

What are some ways an SCR is triggered?

A silicon-controlled rectifier (SCR) can be triggered (or turned on) by forward voltage, temperature, dv/dt (the derivative of the voltage with respect to time), light, or via a gate (the SCR is triggered when sufficient voltage passes through the gate). Gate triggering is the most common method.

What happen when plus ve gate pulse given to reverse baise scr?

You cannot turn an SCR off by reverse biasing the gate. Once it is on (anode to cathode), it stays on until the forward current AND the gate current drops to the required threshold level. That said, you can pulse the anode negatively to turn an SCR off, so long as you don't exceed the reverse bias limits of the device. This is how (photographic) flash devices, for one example, can modulate the duration of the flash.

Can you apply forward voltage when anode current fall to zero in scr?

No. Soon after its anode current falls to zero, the device is not is a state to block the forward voltage due to the presence of carriers in its four layers its still in conduction mode. Thus at first it takes some time to remove excess charge from the four layers. Thus just after its anode currents decays to zero it is unable to block the forward voltage.

Why SCR is not called GCR?

because it is gcr not scr

What is the basic function of the SCR's gate electrode?

The SCR's gate electrode is used to turn the SCR on, i.e. fire it.

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
