AC2DC

AC2DC — AC to DC Converter Board

A simple, compact AC-to-DC converter PCB designed in KiCad. Converts AC mains/transformer output to a smoothed DC output, with an onboard LED power indicator.

Overview

The board implements a classic full-wave bridge rectifier followed by capacitive smoothing:

• Rectification: 4× 1N4007 diodes (D1–D4) in a full-wave bridge configuration
• Smoothing: Electrolytic capacitor (C1) filters the rectified output
• Power indicator: LED (D5) with current-limiting resistor
• I/O: Two screw terminals (J1, J2) for AC input and DC output connections
• Load/bias resistors: R1, R2

Getting Started

1. Install KiCad (v7 or later recommended).
2. Clone this repo and open AC2DC.kicad_pro.
3. Gerbers and drill files for fabrication are in /production — ready to submit to a PCB manufacturer (e.g. JLCPCB, PCBWay).

Safety Note

This board interfaces with AC mains/transformer voltages. Exercise standard precautions when prototyping or handling AC-connected hardware — verify isolation, insulation, and ratings suited to your input voltage before powering the board.
