|Serial No.|Component Details |Specification |Quantity |
|1. |Transformer |220V/12V |1 piece |
|2. |p-n junction diode |1N4007 |4 piece |
|3. |Resistor |3.2KΩ |1 piece |
|4. |Capacitor |1000uf |1 piece |

The main goal of this project is to design an efficient and cost effective 5 volt DC power supply from 220 volt AC source input. The design is completed using a transformer, full wave bridge rectifier, filter with suitable smoothing capacitor and a voltage regulator. After completing the design simulation is performed for the design. From the simulation it is observed that the output wave shape of the DC voltage is very smooth and the value is almost 5.01 V.
Introduction
A power supply is a device that supplies electric power to an electrical load. The term is most commonly applied to electric power converters that convert one form of electrical energy to another. An AC-DC power supply converts alternating current (AC) into the direct current (DC). In general most consumer electronic devices such as desktop computer, mobile phone require a low DC power source. In practical field DC power for electronic devices is most conveniently obtained from commercial AC lines by using rectifier-filter system, called a “DC Power supply”. In this project we are designing a “5
