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
"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...]
