Hello everyone this is @waverunner and welcome to my this #stemgeeks post
In this post, I will tell you how I can convert AC into DC current. We are using electricity in our house and we no little bit about it and that is we use AC power signal but some devices like mobile phone and laptops require to charge DC power signals all DC current so how it converts the signal into another signal that means signals these things I will tell you in this post.
First of all, I have not told you about the amplification of the current I will tell you only about the current conversion from AC powered signal to a
DC power signal because of f someone wants to try to AC power signal into DC power signal and I want to charge their laptop and phones so there is one thing also required to amplification of this far because powered we are using in our home that is 240 to 440 volt and mostly we are required to charge our phone and laptop on their requirement.
Disclaimer
I request you to please take this post only for information without checking voltage don't use it anywhere it may be harmful to you or your devices also.
The process of the conversion of AC signal in two decisional is called a rectifier is a device that converts the signal into a DC power signal how it actually works and how it looks like in this first I will tell you today. To know about this we know first some basic things what type of signal is an AC signal and the voltage diode that we are using to create this device rectifier.
Diode
A Diode it's a component that allows current in only one direction it is made with some combination of semiconductors in which two semiconductors have enough holes and another semiconductor has enough electrons months before the current in one direction electron easily moves to the whole side but when we connect it up terminal of voltage so hole and electron are dispatching birthday they have some electric field attraction because electron have negatively charged and holes have positively charged. So the flow of electron is not enough to flow current that's the reason why the diode allows current flow in only one direction and restrict another direction
AC power signal
The AC power signal is a periodic signal which starts from 0 and reaches the maximum point decrease at 0 and gets the lowest point that is the alternating current actual graph we can say alternating current it's flowing positively and negatively in their time period.
DC power signal
DC current that's been direct current so his graph is like a line parallel with x axis direct current has some period but it is undefined because a line has some period but the period is undefined.
Every current is harmful to the human body but in my opinion comparison to AC current the DC current is more harmful because when will touch the current so it is sinusoidal you can get zero current at some point in time but in DC current it's continuous all time so You cannot get any point zero during connection.
Connection of Diode
Working Principle
Four Diode connected like a square first two node is input and the second two are output which is shown in the picture. I didn't put the side We gave the AC signal and at the output side we get DC signal and how it works let's see.
When is he singing in will be in a positive cycle so diodes that are diagonally are in forward bias that's means currents flow in a positive direction and at the same time the second diagonally diodes are reverse biased that's mean the current direction on that diode is opposite direction so diagonally diode will flow the current in a first half cycle and second half cycle it will be reverse bias and reverse biased diode will be forward bias and this order will continue.
And we got signals which have only positive pulse negative pulse will remove. But it is not exactly like DC signals so we can put some capacitor across it to reduce the impulse of the signal so we can get a similar DC pattern on this graph. This signal is not an exact DC signal but it behaves like a DC power signal. We can use it anywhere that we have the required DC signal.
Thanking You!
