AC-DC-Converter

A simple full-wave bridge rectifier circuit built in KiCad, converting AC input to a smoothed DC output with a power-indicator LED.

Overview

This project takes an AC input through screw terminal J1, rectifies it using a full-wave bridge rectifier (D1–D4, 1N4007 diodes), smooths the output with a 1000µF capacitor (C1), and outputs clean DC through screw terminal J2. A power indicator LED (D5) is driven through a voltage divider (R1: 10kΩ, R2: 2.2kΩ) to show when the circuit is powered.

To manufacture the board, send the contents of gerbers/ to your preferred PCB fab (e.g. JLCPCB, PCBWay). Connect an AC source to J1 and take your regulated DC output from J2. Notes Standard 1N4007 diodes are rated for up to 1A and 1000V reverse voltage — suitable for low-power AC-DC conversion. This is a basic rectifier without voltage regulation; add a linear regulator (e.g. 7805) downstream if a fixed regulated voltage is required. License
