This project presents the design of a compact PCB that converts 220V AC mains to a stable 12V DC output. It includes the key stages of rectification, filtering, and voltage regulation. The goal was to ...

This is a quite simple DC to AC inverter that provides 220VAC when a 12VDC power source is provided. It can be used to power very light loads like night lamps and cordless telephones, but can be ...

The internet is full of such schematics, so this project is nothing special. I try to make it special by providing more explanations and oscilloscope pictures than usually given. The aim of all such ...

Maybe I'm describing a unicorn device here but I have a bunch of devices that run off DC-in of various voltages, and take a barrel jack connector for power. They all have their own wall warts but I've ...
