The objective of this Lab activity is to examine the structure and operation of the Silicon Controlled Rectifier or SCR. SCRs are mainly used in devices where the control of high power, possibly at high voltage, is needed.
24 lut 2012 · The basic operating principle of an SCR can be understood using the two transistor model of SCR, which combines p and n layers. An SCR is a pnpn thyristor. By bisecting it, we see two transistors: one pnp transistor with J 1 and J 2 junctions and one npn transistor with J 2 and J 3 junctions.
