README
ac-dc-converter/README.mdAC–DC Converter PCB
This project is a simple AC to DC converter PCB designed using KiCad.
It converts an AC input into an unregulated DC output using a bridge rectifier and capacitor filtering.
Overview
The AC–DC converter consists of:
- AC input through a 2-pin screw terminal
- Full-wave bridge rectifier using diodes
- Capacitor filter for ripple reduction
- DC output through a 2-pin screw terminal
- LED indicator for DC output presence
This design is intended for learning and academic purposes.
Features
- Full-wave bridge rectification
- Capacitor-based DC smoothing
- Screw terminal input and output
- Simple and compact PCB layout
- Designed using KiCad 9.0
Input / Output
- Input: Low-voltage AC (from transformer)
- Output: Unregulated DC voltage
⚠️ This board is not regulated. Output voltage depends on input AC and load.
Main Components
- Diodes: 1N4007 (×4)
- Filter Capacitor: Electrolytic capacitor
- LED + current limiting resistor
- 2-pin screw terminal blocks (AC input and DC output)
Files Included
- Schematic (
.kicad_sch) - PCB layout (
.kicad_pcb) - Gerber files (for fabrication)
- Project documentation
Tools Used
- KiCad 9.0
Safety Notice
⚠️ This project involves AC input.
- Use only low-voltage AC from a transformer
- Do not connect directly to mains
- Maintain proper electrical isolation and clearance
- For educational use only
