## Introduction: AC to DC Converter=diode Bridge

A diode bridge is a device that changes Alternating Current(AC) to Direct Current(DC). The difference between these two kinds are that, AC is pulsed electricity switching polarities 50-60 times per second.(If you look at electronic devices it says that it runs on 50 Hertz AC)Switching polarities= - to + and + to - 50 times in a second.DC is a continious current coming out.Example batteries.The polarities do not change in DC.The problem with AC is that you cant charge batteries with it.

In this instructable i will show you how to make a diode bridge.

(NOTE: This is not an instructable about how to charge batteries.If you are going to use the device, use it correctly.
For Example DO NOT PLUG IT IN THE POWER OUTLET AND TRY TO CHARGE YOUR BATTERIES SUPERFAST!THE BATTERY MIGHT EXPLODE AND CAN CAUSE INJURY OR DEATH. USE A CORRECT STEP STEP UP,DOWN TRANSFORMER IF YOU KNOW THE VOLTAGE RATING)

## Step 1: Materials

A: 4 diodes(black ones)

B: 4 wires (2 for AC input 2 for DC output)

C: AC source (NEVER USE POWER OUTLET UNLESS YOU KNOW WHAT UR DOING, OR B: YOU ARE GOING TO DIE WITHIN 2 HOURS BECAUSE OF A DISEASE)

D: Pliers( if you dont have any,buy one or rob it from someone)

## Step 2: Twist the All the Diodes' Legs Around Each Other

Get 3 diodes and twist them together striped sided on the bottom, except for the last one.The last one you reverse the striped side.

ARRGH!I cant explain with words!Look at the pictures below!After all, "A Picture is worth a thousand words", so said a person a long time ago.

## Step 3: What to Use It For?

i dunno...i use mines to charge my 10 volt batteries.you can use yours to do other stuff...use your brain!!!think of something!(Ex:use a step up transformer to charge Capacitors and make a welder?)whatever..im too tired.(yawn).good luck making it.some pictures below to show that it works.Goodnight.....(snore)...(snore)...(snore)...(fart)..

## Questions

nice job

i am making electricity producing footwear using piezo discs

piezo produce in ac but to use in dc with this cool circuit

did you complete the amking of shoe from piezo disc did it work? if not i can help and if yes pplz review

Thanks for such a simple diagram. I am working with a circuit for a little project, but I did not have a bridge rectifier handy. I have lots of diodes I have pulled from old electronics, and this has allowed me to do some testing on my circuit. Thanks.

This circuit simply converts the input current (A/C) to a output current of (D/C). Like converting mp4 to mp3. If someone wants to get a current of 2.3vDC from the output terminals he/she has to input the same amount of A/C current through the input terminal.

hi,

I need an output current of 2.8V and a variable current varying from 15 to 25 to 35 A from an input of 220V Single phase supply. Plz draw me a small diagram on how to do this. God Bless u

how to convert 110v ac to 220v dc? need asap. pls. thank you ;)

Is this attached circuit works fine? Any modifications need to be done.... Help me out in choosing the values of resistors & capacitors. Thank you

thanxxx dude.....this really works......helped a lot

Thanks for the post. I am trying to test motors from 240 V AC appliences (e.g. a motor from a washing machine) using DC batteries at a safe voltage would this diode brige be safe to do this.
