In this project, I have explained how to connect LEDs with 220 Volt AC supply with the circuit diagram. I have also explained how to design a transformerless power supply LED 220V AC circuit with calculation.

The LED 220V AC circuit is very simple and efficient. Here I have connected 8 LEDs (5-mm, 3V) in series and supply the circuit using a transformerless power supply.

0.22uF 400V AC capacitor

100uF 35V DC capacitor

560-ohm 1-watt resistor

1M 0.25-watt resistor

1N4007 Diode (4no)

5-mm LEDs (3V) (8no)

Zero PCB

First, I have made the circuit on the breadboard for testing. In the tutorial video, I have measured all the voltage with the multimeter to show how the circuit works.

In this video, I have explained all the details for this LED 220V AC circuit.

To design any capacitor drop transformerless power supply, first, we have to calculate the capacitance value.

How to Calculate the Capacitance value for transformerless power supply?

1. We should know the input voltage (Vrms) and the required output voltage (Vreq) and current (Iout).
