# 230V AC LED DRIVER CIRCUIT WITHOUT TRANSFORMER

This is a DIY 230V LED Driver circuit without transformer. Here i am using 5 led's, you can increase the count. 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.

3. LED specifications are used?

4. you can use ordinary led's

5. what is circuit safe form electric short for my body?

6. sir
if i want to add more leds what are the changes to be made in the cct.

You can increase the count, but after certain limit the light dims.

8. wats that 120r
is it 120 k or 120 ohms??

9. 120R means 120 ohms,
sorry for the trouble...

10. What is the purpose of poly capacitor? Thank you sir for details above.

11. Could you suggest a power supply from 230v to light 5-10 1W High Power white smd LEDs with high efficiency please..

12. Thanks for sharing this information of LED driver. Your given information is helpful LED drivers users.
