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)

(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.

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

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.

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

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.

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

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)

Now our circuit is completed.

Switch ON the Power supply.

This Inverter is working very well.

Thank you
