Making A Transformerless Power Supply

 

Upon surfing the net, I have found this site: http://electroschematics.com displaying their projects on making a Transformerless Power Supply with a 12 volts output voltage and a current of 100mA. We usually see this kind of power supply on a China made model of rechargeable products like flashlights and mosquito killer. This circuit catches my attention because of its application in our work which needs a power supply and we can also use this power low current circuits like some of our projects that don’t needs too much power requirements.

Note: “Be careful, this circuit is not isolated from 220 volts AC. It needs some extra care in handling this kind of supply. Dangerous High Voltage AC.”
