From the project
Two-layer KiCad PCB for converting 12V AC to unregulated DC using a full-wave bridge rectifier, capacitor filtering, and LED power indication.
A compact two-layer PCB designed in KiCad for converting a 12V AC input into an unregulated DC output using a full-wave bridge rectifier and capacitor filtering. The board also includes an LED power indicator and a bleeder resistor across the DC output.
The circuit uses four 1N4007 diodes arranged as a full-wave bridge rectifier to convert the AC input into pulsating DC. A 1000µF electrolytic capacitor smooths the rectified output, while a 10kΩ bleeder resistor provides a discharge path when the input power is removed. An LED with a current-limiting resistor indicates the presence of the DC…
