SPECIFICATION

Experimental Training Board has been designed specifically for the study of D.C. Power Supplies using basic techniques of rectification, smoothing and regulation.
Practical experience on this board carries great educative value for Science and Engineering Students.

Object:

Study of basic techniques of D.C. Power Supplies :
1. Use of a diode as a rectifier (Half wave rectification).
2. Study of full wave rectification using a centre tapped transformer.
3. Study of full wave rectification using a bridge rectifier.
4. Using a zener diode for regulation.
5. To use a transistor as a series regulator.
6. To use a transistor as a shunt regulator.
7. To study methods of ripple reduction.
To measure basic parameters on a D.C. Power Supply :
1. Line regulation.
2. Load regulation.
3. Ripple factor.
