9V _Power Supply

Project: 9V Power Supply Circuit

This project involves designing and building a regulated 9V DC power supply from an AC input. The circuit uses a transformer to step down AC voltage, a bridge rectifier to convert AC to DC, a smoothing capacitor to filter ripples, and a voltage regulator (7809 IC) to provide a stable 9V output.

The project demonstrates skills in:

Power electronics and circuit design

AC to DC conversion (rectification & filtering)

Voltage regulation using linear regulators

Practical soldering and testing of circuits

This type of power supply is essential for powering microcontrollers, sensors, and small electronic devices.
