From the project
AC to DC converter PCB (full-wave bridge rectifier) — KiCad project
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.
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
