How to Make 220V INVERTER Using 3055 Metal Double Transistor

Hii friend,

Today I am going to make an inverter circuit using 3055 Metal Double Transistor.This inverter is working very well.

Let's get started,

Step 1: Take All Components As Shown Below

Components required -

(1.) Transformer - 12-0-12 (2A) x1

(2.) LED - 230V (5W) x1

(3.) Resistor - 330 ohm x2 (Here I am 1/4W for demonstration but use 3W Resistor)

(4.) Transistor - 3055 (Metal) x2

(5.) Power supply - 12V DC

Step 2: Circuit Diagram

This is the circuit diagram of this project.

Connect all components according to this circuit diagram.

Step 3: Connect Both Transistors

Solder Emmiter pin of both transistor as connected in the picture.

Step 4: Connect 330 Ohm Resistor

Next we have to connect 330 ohm resistor between Base pin of one transistor to collector pin of other transistor as solder in the picture.

Step 5: Connect Another 330 Ohm Resistor

Solder again 330 ohm resistor between collector pin of 2nd transistor to Base pin of remaining transistor as solder in the picture.

Step 6: Connect Transformer to the Circuit

Next Solder 12-Wire of transformer to collector pin of transistor-1 and

Solder another 12-wire of transformer to remaining collector pin of transistor-2 as solder in the picture.

Step 7: Connect 230V LED

Next connect LED to the secondary coil of transformer as solder in the picture.

Step 8: Connect Power Supply Wire

Now connect power supply wire to the circuit.

Connect +ve clip to 0-wire of transformer and

-ve clip to common Emmiter pin of transistor as connected in the picture.

(Match connections with the circuit diagram)

Step 9: Give Power Supply

Now our circuit is completed.

Switch ON the Power supply.

This Inverter is working very well.

Thank you
