SCR (Silicon Controled Rectifier)

The SCR (Silicon Controled Rectifier) The SCR is a 4 layers semiconductor device which behaves almost as an ideal switch. Thyristor symbol and structure are shown at right. A = anode, G = gate and K = cathode. Basic Operation of a SCR To understand the SCR operation, the following picture shows an equivalent circuit. An IG current is applied […]
