Triggering of Thyristors or SCR Triggering

September 1, 2021 By WatElectronics

Silicon Controlled Rectifier or SCR

The SCR turn ON method like SCR triggering or triggering of the thyristor is used to bring a silicon-controlled rectifier from forward blocking mode into conduction mode. In conduction mode, SCR can be characterized through less voltage drop, the impedance across anode, cathode & high anode current. The anode current value can be determined through the load and it permits the flow of current. So, a silicon-controlled rectifier in forward conduction mode is known as its ON state & it … [Read more...]

What is Gate Turnoff Thyristor & Its Working

March 12, 2021 By WatElectronics

Gate Turnoff Thyristor

"Thyristor" is a semiconductor device that is popularly used as a switch in power circuits. With alternating layers of P-type and N-type materials, the thyristor is designed as a four-layered structure. It is available as both two-lead and three-lead designs. The three-lead design of the thyristor consists of an anode, a cathode, and a Gate lead. The thyristor usually starts conducting when the gate lead is triggered with the current and once turned ON, the thyristor conducts continuously until … [Read more...]
