Because it can control input voltage in both halves of cycle.
it conducts in only one direction. it can also be used as a switch and made to not conduct at all.
That is used as a switching device. They are very common in Inverter circuits and can switch up to 1000's of amps.
The SCR's gate electrode is used to turn the SCR on, i.e. fire it.
A thyristor is a type of semi-conductor and is used in a circuit to control the application of electrical power to a load. They are often found as the switching element in light dimmers and can be used as control elements in power supplies (variable or regulated). Types of thyristors are diacs, triacs, sidacs and SCRs (silicon controlled rectifier).
scr is a silicon control rectifier used to control the rectifing voltage.. its a bidirectional device can use it for both the directions......
A SCR's (Silicon Controller Rectifier) name hints at the answer. As a rectifier (diode) current can only pass in one direction. There are devices at can pass in both directions, and typically they are a pair of SCR's wired in opposite polarity.
Because it can control input voltage in both halves of cycle.
An SCR (Silicon Controlled Rectifier) acts like a switch when turned on. It can also be used as a rectifier.
I's a electronic component that act like a controlled diode. It can be used as a switch on some applications, but with some limits. 1- A SCR is a diode, and as such, it only conduct in one direction. 2-The SCR only turn off when the current passing it reaches zero.
it conducts in only one direction. it can also be used as a switch and made to not conduct at all.

Essentially an Scr is a solid state switch that will only allow current to flow in one direction. A triac is essentially two scr's in Anti- parallel that allows current to pass in both directions.

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
And SCR will conduct appreciable current when it is gated "on" and thus "told" to conduct. A silicon controlled rectifier(SCR) is an electronically controlled DC switch, and the gate is the terminal to which the control voltage is applied. Use the link below to learn more.
