README
README.md⚡ AC to DC Converter
A simple AC to DC Converter designed in KiCad using a bridge rectifier, filter capacitor, and LED indicator. The circuit converts AC voltage from a transformer secondary into a smooth DC output suitable for low-power electronic applications.
⚙️ How It Works
- AC voltage is supplied from the transformer secondary.
- Four 1N4007 diodes form a full-wave bridge rectifier.
- The filter capacitor smooths the rectified voltage.
- The LED indicates that power is available.
- The DC output is provided through the output connector.
✨ Features
✔️ Simple and beginner-friendly design
✔️ Full-wave bridge rectification
✔️ Reduced ripple using filter capacitor
✔️ LED power indication
✔️ Designed using KiCad
🛠️ Components Used
- 4 × 1N4007 Diodes
- 1000 µF Capacitor
- 10 kΩ Resistor
- 2.2 kΩ Resistor
- LED
- Input & Output Connectors

Questions
How big is the AC to DC PCB?
It measures 41.7 × 32.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the AC to DC use?
12 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the AC to DC KiCad files?
From the Saroja-J/AC2DC repository on GitHub, at the commit this page was made from: the board is AC 2 DC/AC to DC.kicad_pcb and its schematic AC 2 DC/AC to DC.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the AC to DC design in my own project?
Its repository states no licence, so its author keeps all rights: ask Saroja-J before reusing the design.
