Abstract:-
Our varying industrial needs demand more precise control of the outputs of our basic electrical prime movers i.e, THE MOTORS. Basically dc motors are easy to control compared to their ac counter parts, but they have their own limitations with increase in capacity. Conversely ac motors in particular squirrel cag ....etc

15-STEP DIGITAL POWER SUPPLY

INTRODUCTION
This circuit will obtain variable DC voltage from 1.25v to 15.19v in reasonably small step.
The steps are according to binary codes.
These codes are obtain using Up Down counter.
This circuit works on the digital principles as we are using binary codes.
OBJECTIVE
This circuit use to we can obtain the 15 step from 1.21 to 15.19v output voltage.
This circuit give variable output voltage. (+ve) Positive and (-ve) Negative
Use LED to indicate variable 15 step voltage ....etc
