How to Make 220V to 12V Converter reception | DIY Circuit to Convert AC ...

DIY Circuit to Convert  220V AC to 12V DC.......

How to Make 220V to 12V Convert project uses four diodes to make one Bridge Rectifier to transfer AC power to DC power. Also, we use capacitors to remove ripples in the circuit. After 240v to DC 12v Converter electrical Diagram, we need to use one 5v voltage regulator to give 5v DC output from 12v DC output. AC to DC Converter without a transformer Circuit Diagram.
