Hello friends i will present today how to make a simple inverter called "the classic inverter"
that everybody can do it at home with some components that are cheap easy to find
and no special skills needed.
This is the most simple inverter diy project that you can make without any skills in electronics so easy and cheap but it comes with a price you have to buy some components and wire them together and this is it you are good to go just prepper your battery and led bulbs.

Step 1: The Oscillator
An electronic oscillator is an electronic circuit that produces a periodic, oscillating electronic signal, often a sine wave or a square wave. Oscillators convert direct current (DC) from a power supply to an alternating current
(AC) signal. They are widely used in many electronic devices. Common examples of signals generated by oscillators include signals broadcast by radio and television transmitters, clock signals that regulate computers and quartz clocks, and the sounds produced by electronic beepers and video games.
In my opinion the hart of any inverter is the oscillator if you got this part right you are good to go thats way
i choose this already made oscillator
http://amzn.to/2qXBUKY is not expensive and save you lots of research parts testing and so on
On the link you will find all the details .
It has 3 pins VCC,GND,OUT and some jumper witch i connect in the second position
VCC is the + terminal of the power supply in my case was just 5v
GND is the - terminal
Out is the pulsed 5v signal
After this step you will connect to the transistor.
Step 2: The Transistor 2n3055
The 2N3055 is a silicon NPN power transistor intended for general purpose applications. It was introduced in the early 1960s by RCA using a hometaxial power transistor process, transitioned to an epitaxial base in the mid-1970s. Its numbering follows the JEDEC standard It is a transistor type of enduring popularity.
Packaged in a TO-3 case style, it is a 15 amp, 60 volt (or more, see below), 115 watt power transistor with a β (forward current gain) of 20 to 70 at a collector current of 4 A (this may be 100 to 200 when testing using a multimeter. It often has a transition frequency
of around 3.0 MHz and 6 MHz is typical for the 2N3055A; at this frequency the calculated current gain (beta) drops to 1, indicating the transistor can no longer provide useful amplification in common emitter configuration. The frequency at which gain begins to drop off may be much lower, see below.
Ok so you have the transistor 2n3055
http://amzn.to/2r7bkiX now you have to connect it as a transistor current limiter picture number 3
Step 3: The Transformer
A transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction. A varying current in one coil of the transformer produces a varying magnetic field, which in turn induces a voltage
in a second coil. Power can be transferred between the two coils through the magnetic field, without a metallic connection between the two circuits. Faraday's law of induction discovered in 1831 described this effect. Transformers are used to increase or decrease the alternating voltages in electric power applications.
Since the invention of the first constant-potential transformer in 1885, transformers have become essential for the transmission, distribution, and utilization of alternating current electrical energy. A wide range of transformer designs is encountered in electronic and electric power applications. Transformers range in size from RF transformers less than a cubic centimeter in volume to units interconnecting the power grid weighing hundreds of tons.
In the video and instructable the transformer used is recycled from an car auto battery charger like this
http://amzn.to/2qsipqt but you can buy them from amazon or ebay,or harvest them from old radio,power supply,chargers,and so on.In this project we gonna use the transformer in revers meaning we gonna supply 12v to the normaly output,and the main 220v is gonna become out 220v output.
oK SO WE ARE GETTING CLOSE TO THE CLASSIC INVERTER
Step 4: 12v Battery
We choose for thos project a classic 12v lead acid battery but you could be different deppending on what you have
also very important the transformer from the previous step needs to be the same voltage so if you power with a 12v battery you will need a 12v output transformer,if is 6v power you will need a 6v out put transformer and so on.
At this spet we will connect the transformer and battery and the previous components and we are almost done
if you want to view a different method of charging 12v battery pplease visit NoSkillsRequired youtube channel.
Step 5: The Final Step
You should have at this step the oscillator connected with his own power supply,the output to the transistor 2n3055
but can be any npn power transistor,connected to the correct transformer,and powered with the propper power supply,if any of this missing please review the steps.
