my friend told me to or simply challenged me to make a converter that is easy .i can not make difficult things but this one was so easy that i made it in almost three minutes.this one was an ac to dc converter.it costed me only a few dollars.just the cost of four diodes.it is very easy and no trouble for soldering. so i want to share it with you all.so lets get started

## Step 1: Ingredients

things needed:
1)four diodes of any size

tools needed:
1)pliers

thats all you need

## Step 2: Information About Diode

diode is a electronic ingredient that helps electricity flow in one way.there are two leads one positive and other negative.onthe diode one one side there is a white coloured small band.that is the negative side of diode .a hand drawn figure of it is given below

## Step 3: The Diagram of the Circuit

this is the drawing of the circuit.the circuit can be made using this diagram even easier

## Step 4: The Main Circuit

firstly take the first diode and second diode and join their negative leads together.lets name this negative sides.just name.

## Step 5:

now take the 3rd and 4th diode and join their positive sides together as shown,lets name this end positive end

## Step 6:

now take the four diodes.there are two free ends one the first and second diode that is the two positive ends.now join these positive ends to the free negative  ends of the 3rd and 4th diode.like in the picture now lets name these ac leads

## Step 7: Identifiying the Poles

the circuit is complete.the joining place that was named ac leads are the ac input.ac electricity are to be given through these two ends.the end named negative side is the positive dc output that is positive dc electricity will come out of it.and the end named positive side is the negative dc output.that is negative dc electricity will come out of it.so your ac to dc converter is ready.have fun with it
I want to make a 240v ac to 12v dc converter. Can yoy help me???
Can we run a led light script with it
This would make for a terrible dc supply. First off a transformer ia needed to drop the voltage down to a useful dc level. Some output capacitance is required to keep the output constant
<p>Yeah, I should have added those at first. I made this when I needed to rectify ac current to Dc for my homemade generator project. So for that it worked quite well, but if you want to work with wall outlets, you of course have to change up the circuit. </p>
<p>wat is the output volttage??</p>
0 volts
<p>It does not have any output voltage unless you input electricity. The only thing this circuit does is convert A.C electricity to D.C. electricity. So it would be useful only when you need to convert A.C electricity to D.D electricity for any electronics..</p>
Should there be any specifications of the diodes if i want to convert 220v AC to 220v DC, or any diode could do?
Salam pls can u help me with simple dc to ac converter circuit diagram
<p>Using this example and a few others, I made an ac to dc converter. The pictures shows from top to bottom the important parts of a converter. Transformer, bridge rectifier, and capacitor. The light is just for safety so that I know when the power is on. </p>
<p>Great! So I think your converter is a Step down ac to dc converter. So what's the output and input of the converter? And what things did you use it for? Once again you did a great job in that creation.</p>
<p>While you're right that this converts AC to DC, I wish you would make it clear that this circuit would not work for any piece of electronics. This creates an un-regulated (not constant) high voltage 120V DC pulse that pulsates betweeen 0 and 120V at 120Hz.</p>
Very nice job Argha halder.. I am not an EEE student but i can easily understand how to make these circuit.. Realy i enjoyed to make my own AC to DC Converter. Thank You...by A.SenthilKanth, from Tamilnadu.
Thank you! And it is my pleasure if you found the project fun.
<p>will this be able to run motors?</p>
<p>If you are willing to use a wall outlet to run a motor , then yes you can use it in middle to run a dc motor. But you must have a voltage converter to decrease the voltage, I am not liable for any damage.</p>
<p>will this be able to run motors?</p>
<p>wow its cool and cheap also!!!!!!!!!!!!!</p>
<p>Thanks!! Have fun using it!</p>
Hi friend. Thank u for ur inst. I want to make it to convert 12 v ac to dc from my car to generate 220 v from my pc power backup. Does it work
<p>Yap it will convert that ac to dc, but use a big high voltage diode to do that, otherwise it might burn or stop working. Otherwise good luck! and welcome..</p>
<p>Can the same device be used for converting DC to AC?</p>
<p>No, you can not change dc to ac with this device,, </p>
<p>Most kids challenge each other to beat video game scores. Your friend challenged you to make an easy ac-dc convertor. That's awesome! ^^</p>
<p>Yeah, having science loving friends are pretty awesome,</p>
While this will work I would highly recommend soldering these leads as there can be small gaps that cause arcs and can cause issues... <br>Other than that, nice work.
thanks for the suggestion! <br>
will it work for dc to ac??? <br>
nope.
Is the output constant or does it turn on and off at the rate of the current?
I added a 2000uF output filter cap. Notice the change in the VOUT signal &amp; the current flow through the 120ohm resistor
See the picture for Diode Bridge rectifier <br>https://www.instructables.com/files/deriv/FX6/4FDY/HINNZAYF/FX64FDYHINNZAYF.SQUARE.jpg :
you will get 120hz (USA) or 100hz (Europe) DC voltage to filter it you will need to add some caps e.g. i always add 2000uF for 1A so if i have transformer that gives me 20V 2A i will put 25V 4000-5000uf cap
i dont know that much about it as i only saw a real small converter using this circuit.but i think the output is constant.
This is diode bridge aka Graetz circuit
yes it is
