SCR CHARACTERISTICS APPARATUS WITH REGULATED POWER SUPPLY

Description

The SCR Characteristics Apparatus is a standard laboratory setup designed to study the V–I characteristics of a Silicon Controlled Rectifier (SCR) under forward blocking, forward conduction, and reverse blocking conditions. The apparatus enables accurate determination of important SCR parameters such as breakover voltage, latching current, holding current, and gate triggering behavior.
It is an essential experiment for power electronics, solid-state electronics, and electrical engineering laboratories.
