SCR CHARACTERISTICS TRAINER

SCR CHARACTERISTICS TRAINER

Category: Electronics

Model No:IE-112

Experimental Training Board has been designed specifically to study characteristics of SCR - Silicon Controlled Rectifier . The board is absolutely self contained and requires no other apparatus. Practical experience on this board carries great educative value for Science and Engineering Students.

Product Description

SCR is a three terminal device; anode, cathode and gate as shown in figure. SCR has built in feature to turn ON or OFF and its switching is controlled by biasing conditions and gate input terminal. This results in varying the average power delivered at the load , by varying the ON periods of the SCR. It can handle several thousands of voltages and currents. SCR symbol and its terminals are shown in figure.   Depending on the biasing given to the SCR, the operation of SCR is divided into three modes. They are

1.     Forward blocking Mode
2.     Forward Conduction Mode and
3.     Reverse Blocking Mode

Features

  • To obtain the V-I characteristics of SCR and find 
  •  the break over voltage and holding current.
