D.C Supply (9v & 12v)

D.C Supply (9v & 12v)

In this kit we are using a.c. supply 230v single phase to convert it into d.c. supply by the circuit which is given below.

In this circuit we are using transformer to step down the a.c. supply which is centre tapped and a full bridge rectifier is connected which is conveting it into d.c. supply.
The positive cycle will be fed to the positive half cycle i.e. ic 7812 and the negative half cycle will be fed to the negative half cycle i.e. 7912. Thus, output is obtained.
