.ppt   Regulated power supply.ppt (Size: 23 KB / Downloads: 139) do you want the power point presentation of Regulated Power Supply.....see here....


Regulated power supply
The major blocks of power supply are given below
Transformer
Rectifier
Filter
7805 voltage regulator

Transformer
Transformer is a electromagnetic device which induces the voltage due to magnetic field present between primary and secondary windings.

It has two windings called as primary winding and secondary winding. We are giving input 230v input voltage at primary side. The output of transformer is 9v(ac only).

In this project and implimentation we are using 9v step down transformer


We have two types of transformers
Step up transformer.
Step down transformer.

Step up transformer:
This transformer will step up the voltage that is this transformer will increase the voltage.

Step down transformer:
This type of transformers will step down the voltage. That is this will convert high voltage in to low voltage.

Mostly for project and implimentation purpose we are using only step down transformer.
