AC-DC Converter
We need DC power supply for electronic circuits for that we use either a battery or a Step-down transformer. But cost effective power supply circuit can be designed to power low current devices like LED lights or similar simple circuits. Here is a Transformerless power supply using a Resistor and a few components to make a 12 volt power supply from 230V AC. It is too simple, light weight and can power simple circuits including Transistor and IC based circuits .The circuit is highly lethal and can give a fatal shock. Therefore, it should be constructed only if you are competent to handle high volt circuits.
