EXPLAINED : Inside a cell phone charger

[@user-zj1cz9fc6u]

Simple and to the point, at the same time very informative. Good job man!

[@manasdelta]

we use smps in charger not only to make its size smaller but also use it in wide voltage range(90v -270v).the 4 pin component which you called ic chip is known as opto coupler .and which you called normal transformer is actually called flyback smps transformer .normal transformer use iron/still as core ,but smps flyback transformer use ferrite core.

[@brainamplifier]

manasdelta thanks for your input and constructive feedback. please subscribe the channel if you like the effort.

[@BharathRamMS]

Is opto-coupler a type of microcontroller?

[@ranitkarmakar8583]

what is the ratings, pin diagrams of the flyback smps transformer ??

[@matlabkuchbhi3060]

Bharath Ram no

[@vg1881]

@@BharathRamMS No.. it is a coupling device ...or simply saying a voltage transmiter (connector) with isolation...Direct contact is avoided by means of IR based light sensing diodes..

[@rohitimandi]

Thank you so much particularly for explaining about the size.

He used MOSFET i think As his frequency was high.

[@RATANKUMARRateria]

Very nicely explained in lucid terms so that beginners also can learn....how much is the high frequency produced by MOSFET..?

[@kerrya.s3164]

[@metalheadgamer5751]

Question what would happen if you put 12 Volt DC into the input side were the AC is supposed to go? What would the output be?

[@shiftgood1]

Very nice, pal. No excess rebadge, you INCLUDE paperwork, your explanation is perfect-teem style. You inclue simple theory, and you add A PERTINENT QUESTION. DARN, BUT YOU get an A. My own thought, the electronics industry has a bunch of playboy/girls in it, so YOU should be in showbiz!!!! Of course, I speak in the name of the changes IN THE WORLD, Again, this takes me back to old timey teaching/speaking.

[@GoogleAccount-rh2ls]

Excellent video, Superbly explained 👍

[@middleclassic]

I am only 2 minutes in but it seemed to me that while you were explaining what each individual part is you might as well acknowledge the USB output connector too. I know what it is and the fundamentals of how that particular piece of this puzzle works, but for those who do not know what it is, a quick intro to it like the rest might help someone. Jus sayin' ... :-) I truly admire the fact that you do not want to waste peoples time with a long drawn out video. But there were a few times where you just motored through a sentence or two leaving my ears in the dust. Throw in the fact that I have not seen my Indian friends in years nor have I visited Pioneer Blvd and I had trouble keeping up. Of course that one is on me :-) But yeah, almost sounded like you plugged yourself into one of those chargers you were going fast! But I'll take fast over a long drawn out video any day of the week. I should add that I found this a very informative video as I did learn a couple things. Thank You and Thumbs Up!

Hi, great explanation! I am looking for a circuit just like that, but the newer chargers have a lot of IC components that are too tiny to work with. Any idea what charger you used for this? Thanks!

[@brainamplifier]

It's an old cell phone charges with pin. This video was made 3-4 years back

[@bindurajeevan4423]

tnk u sirrr I have a doubt sir, MOSFET or simply transistors are used in the circuit to convert the 220V nonpulsating DC to 220V AC having much more frequency nna? So that the transformer can recieve AC

[@MAHESHmahesh-cl6ht]

Sharma Sir very nice video all the best

[@mnmurph]

Thanks But, do you know the video's sideways for most of the video? Maybe make a new video she replace this one or link to a fixed video, if you get the chance, because this is good stuff

[@MahakaalAstrologyservices]

In simple ,if U see the mobile charger,here the Input voltage at 240 Volts at 50/60Hz frequency is first fed to Input Rectifier stage, Which converts 240 Volt AC to 240 Volt DC. This 240 DC voltage is fed to a High Frequency Switch which converts this DC to High Frequency AC at 240 Volts with a frequency between 50KHz to 1MHz, So now we have 240 Volt AC at a higher frequency. Here comes the Switched Mode Transformer. These Switched Mode Transformer(SMT) are capable of handling higher frequency. So this SMT will now step down the 240 Volt AC at Higher frequency to required Output AC voltage at higher frequency. And the output AC voltage is now converted to DC using output rectification and filtering circuit. The DC output voltage is fed back to the control circuit which gives the firing pulse for the High Frequency Switch. Thus achieving AC to DC conversion

[@BharathRamMS]

Excellent explanation. Thanks for this.

[@electricianhq7049]

How is the signal still AC after it leaves leaves rectifier? Doesn't the rectifier change the AC to DC? But if it was DC the transformer wouldn't work because it needs to be AC. Please response.

[@manoharmishra8172]

is it necessary everytime to convert ac to dc and then back to ac for changing frequency?

[@brainamplifier]

yes. . if you want a similar waveform ( i.e. if input is sinusoidal and we want sinosoidal output of different frequency) of different frequency.

[@jayantanath9]

brother the white part of the diode emmites positive charge current not the negative charge current optocoupler is not a microcontrooler it is connecting device through led light inside of it

[@kabandajamilu9036]

So nice explanation

[@followdream161]

I never forgot SMPS circuit after watched your video. thank you

[@rakeshsingh-ji7jr]

can you let me know what should be the value of components used (value of input resistor,capacitor).What is connected to the gate of the mosfet?.Also is it possible for you to share a seperate video on how does a PT works in such a application.Thanks in advance.

[@MsSrikant123]

Sir, Please can you explain how the transformer operates in the adapter circuit? It has 2 windings.Why the second winding is used? I want to know the detailed operation.

[@ashishitD]

noice................can we just plug a bare li ion battery to the charger...........i mean like is it safe?..............overcharge,heat,etc protection?

awesome explaination dude

[@ngocsang163]

It's really easy to understand the concepts without reading ton of papers about microelectronic

[@pumpkin5484]

Hey , great vid. To which frequency is the Mosfet output changed to ?

[@ganeshhojage5005]

pump kin bro it's about 1khz frequency and due to the such a high frequency Ac only one diode and one capacitor is use to convert it into DC at last step not need to use full bridge rectifier at last stage Hope u understand

[@indraiahlingampally2900]

In every charger bridge rectifier is used?????

[@SrijanSingh_9001]

Baki ka nahi pata par mujhe toh simple me samajhna tha woh tumne samjha diya toh thanks

[@quantum_quest7]

At Last stage I.e., before going to input there is only one diode that means half wave rectifier!!! Why????? There should be full wave rectifier isn't that??☺

[@RohitVairagar83]

[@mastershoka2939]

The diodes are dealing with 230v AC and the DC current is again being changed to high f AC for transformer.as we know transformer converts AC to AC which means the conversion requires another rectifier for making it DC but there is none

[@prasana4047]

Brother do more video like this stuffs really interesting!!

[@robertgillan9672]

[@NagendraKumar_979]

Thanq sir. that's a great explanation

[@trippermostafiz]

Is there any polarity issue of the input of mobile phone charger ? Like Phase to one side of the plug & neutral to another side of the plug. I have one xiaomi charger in which if I connect it to the socket like a way, the charger gets more hot; but if I interchange the charger plug to the socket in another way; then its become normal condition. Actually I wanted to know any internal circuit arrangement where AC phase & neutral has a certain arrangement.

[@DagamerJc22]

BRROOOOOO SLOW TF DOWN. LMFAOOO

[@miguelgarduno1786]

Wrong you first need to step down voltage before rectifying with bridge rectifier

[@nickpierpoint4116]

So is the mosfet creating the AC signal using pulse width modulation?

Why go from ac to dc back to AC then back to DC? Why not just AC to stepped down AC (by transformer) then to rectifier (DC)?

[@Farhan9709]

nice video and good explanation

[@MahakaalAstrologyservices]

Awesome Elaboration but u have skipped the resistor part in input Section of AC which is fusible resistor and frequency is directly proportional to the size of transformer

[@ishworshrestha8361]

Lovely explanation 👌👌👌

[@vamsikrishna5391]

I have 2 doubts 1.after capacitor y can't u keep just regulator and get DC output so that extra transformer circuit is reduced. 2.once we have designed our transformer output is constant. but I found in our trains having 110v DC socket

[@brainamplifier]

+vamsi krishna as our mobile need 5v dc, we have to step down the 110v/230v supply. To do that we have to use transformer.

[@harshsharma5768]

Bhai mosfet doesn't convert dc to high frequency AC , it converts that dc to high frequency pulsating dc.. which acts like ac, as voltage is changing from 0 to particular value ... After rectification voltage never goes in negative side so there is no ac going in transformer , its pulsating dc.

[@amanmishra672]

Sir isme aisa kya hota h jo local charger ke samaan or original charger m kon se samman ka fark hota h

[@AkP88865]

Who controls the Mosfet? The IC. or you could say the brain of the charger.

[@prakashgoud1111]

nice work sir...... try to explain about new mobile turbo charger in ur next video

[@himanshujahagirdar6261]

i have a doubt why not just use a dc transformer instead of converting to ac using a bridge rectifier?

[@Sean-fx6el]

can i put the transformer before the rectifier so i dont have to use mosfet and all i need is capacjtor to filter the rectified signal??? is that possible?

[@ericfernandes3966]

Shouldn't the transformer be in the beginning of the circuit like a bridge rectifier. You said the transformer doesn't work on DC , then if the transformer was in the beginning it will work.

[@vishnupriyatummala801]

If u do that happy diwali in advance cause I had experienced this😂😂😂😂(I had blasted that SMPS transformers) the reason for that is we need low voltage with high frequency...... It is not AC actually it is a square wave like a pulse or pulsating DC(0n-off-on-off-on.....)....By this on off (fast switching)we generate high frequency....

[@kuarashi]

what the??? that is not an ic bro that is a PHOTOCOUPLER

[@brucekinguploads781]

What material is a phone charger head pins made of this is the part that will be plugged in l am speaking of

[@TheJavaSync]

Missing point : You don't explain how the Gate that Mosfet switched - especialy in that circuit

[@Vidya1939]

Yes I too agree with u, how mosfet is switched?? From where get signal is produced

[@prasana4047]

Bruh the mosfet gate triggered by IC555 timer typically the timer will generate PWM pulse signal and this will go through the gate of the mosfet to trigger the conduction between Source to drain...simple MOSFET is a switching device that's all 😊
