Overview
Rectifier AC to DC is an open-source printed circuit board by Hawk453, from the Hawk453/Rectifier_AC_to_DC repository on GitHub, published under the MIT licence. It is a 2-layer board of 90 × 62 mm with 11 parts on 9 nets, routed with 25 tracks and 2 vias.
It is built around the TY-304P. Its parts include 3 connectors, 2 capacitors, 2 diodes and 2 switches.

README.mdFull-Wave Rectifier KiCAD Project
This repository contains the KiCAD project files for a full-wave rectifier circuit. The circuit is designed to convert an AC input to a DC output and features a switchable filter capacitance to demonstrate the effect of different capacitor values on the rectified signal.
Features
- Full-Wave Rectification: Utilizes a bridge rectifier configuration to convert the full AC waveform into a DC signal.
- Switchable Capacitance: A slide switch allows for toggling between a 100uF and a 1000uF filter capacitor. This is useful for demonstrating how capacitance value affects the ripple voltage of the DC output.
- BNC Connectors: The board uses BNC connectors for both AC input and DC output, making it easy to connect to standard lab equipment like function generators and oscilloscopes.
- Clear Silkscreen Labels: The PCB is labeled to indicate the function of the switch and the input/output connectors.

Circuit Overview
The circuit takes an AC signal, passes it through a transformer (TR1), and then rectifies it using a full-wave bridge rectifier (diodes D1, D2, D3, D4). The rectified DC signal is then smoothed by a filter capacitor (C1 or C2). A switch (SW1) allows the user to select either the 100uF capacitor (C1) or the 1000uF capacitor (C2) to see the difference in filtering. The output is available at a BNC connector (J2).
Usage
- Provide an AC input signal to the "Signal In" BNC connector (
J1). - Use both the slide switches simultaneously (
SW1andSW2) to select the desired filter capacitance:- Up Position: 100uF (
C1) - Down Position: 1000uF (
C2)
- Up Position: 100uF (
- Observe the smoothed DC output from the "Signal Out" BNC connector (
J2).

Questions
How big is the Rectifier AC to DC PCB?
It measures 90 × 62 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Rectifier AC to DC use?
11 parts, built around the TY-304P. 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 Rectifier AC to DC KiCad files?
From the Hawk453/Rectifier_AC_to_DC repository on GitHub, at the commit this page was made from: the board is Rectifier_AC_to_DC.kicad_pcb and its schematic Rectifier_AC_to_DC.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Rectifier AC to DC design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
