ELECTRONICS SCR : INTRODUCTION AND WORKING PRINCIPLE
Praful T. SonawaneTybsc Physics
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
