230V LED DRIVER CIRCUIT


Here i am presenting you a 230V LED Driver circuit without transformer. Here i am using 5 led's you can increase the count at your convineance. Due to the absence of Transformers we can reduce the cost and size of the circuit considerably. As we all know LED's are Cheap, efficient and cool device with low power consumption. So we can reduce our electricity bills to a great extent.

The circuit is powered by 230V 50Hz ac supply, so be careful while troubleshooting this project.

Led's commonly works only in DC, so we have to convert the alternating current to direct current and step down to a safe value before applying to the led sequence.

The circuit mainly consisting of 5 led bulbs, a bridge rectifier and a filtering network with voltage regulator.



The bridge rectifier is used to convert alternating current (AC) to pulsating DC. It is made possible by means of rectifying diodes (D1 to D4 1N4007)


The filtering is made possible by means of a capacitor (47uF). It is used to eliminate the ripples coming from rectifier circuit.

After regulating the filtered voltage using a zener diode, we get an almost direct current suitable for LED's.
