Etymology of the Word Thyristor A thyristor is a solid-state semiconductor device with four layers of alternating N and P-type material. The thyristor or Silicon Controlled Rectifier (SCR) was proposed by William Shockley in 1950 and supported by Bell Laboratories‚ formerly known as AT&T Bell Laboratories. It was developed in 1956 by power engineers at General Electric (G.E.) led by Gordon Hall and commercialized by G.E. ’s Frank W. "Bill" Gutzwiller (1). There are various types of thyristors;

triggered when the protective circuit is opened. Circuit Operation:- The circuit consist of a n-p-n transistor‚ an alarm working on 6V DC and a SCR (Silicon Controlled Rectifier). The transistor is biased in voltage divider mode. the out put is taken from the emitter which is fed to the SCR gate. The transistor biasing circuit acts as a voltage follower to the SCR. When the protective circuit is closed‚ the transistor works on near cut-off stage. It acts as a open circuit. When the protective circuit
