SCR

• Full form : Silicon Controlled Rectifier

MAIN APPLICATION

• Switching device• Amplification

BASIC

• Rectification is the process that convert alternating current to direct current.

• SCR work as a rectifier as well as transisitor.

Electronic Symbol and Orignal SCR

Internally structure:

HOW SCR WORKS

• Case 1) When Voltage at anode cathode is non zero and voltage at gate is zero.

• Case 2) When voltage at anode cathode is non zero and voltage at gate is also non zero.

CASE 1

CASE 2
