## Introduction: Mini Cheap Ac to Dc Converter

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

## Questions

The bridge rectifier is so useful. I work on generator control units (GCU's) that regulate generator output on aircraft and some of them use this configuration in a ground fault detection circuit. Some capacitance across the output would be helpful to keep your voltage level constant and soldering is always the best way to go but way to go to solve the ac to dc problem.

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

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.

wat is the output volttage??

0 volts

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..

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

why we didn't use center-tapped full-wave rectifier instead of bridge??

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.

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.

will this be able to run motors?
