This is the most amazing explanation I've ever seen , now I understand how the use of small transformers is possible instead of big ones and how the switching process works with the transformer which was a little bit confusing for me before , thank you very much
There should be a resistor at the input to reduce the current, because that circuit will be overloaded with current which the diodes and transistors could not handle
Thanks for the wonderful explanation, prof. Still I am confused as to how capacitor C1 gets charged from the other side with DC current from S1 then turns on transistor T1 from the other side
do devices have this same process too for example, charging 5V but the device only need 3V, is it gonna overvolt charge or the device has regulator to step down V?
Another way to think about frequency and transformers is to think of a ruler hanging off of the edge of a table. The further is hangs off the edge the slower it will wobble if you apply a force to it and then let go. The more of it to pull onto to table, the faster those back and forth movements (frequency) will go. Larger objects have a lower natural frequency, smaller objects have a higher frequency. The smaller the object (transformers here) the faster you can switch it.
although I understand everything one thing is still confusing me. The capacitor below T1 will be charged by the secondary voltage. The current will pass through that capacitor and the base resistor to fully turn the transistor T1 on. Won't the capacitor be open after some time because this is DC voltage?
Nicely spoken by an AI Voice, as Americans would only refer to their voltage as 120V not 230 or 240, plus a spoken grammatical error at the end of the video and no one ends a sentence on a higher flat tone :) ( unless your Australian) but still, an interesting look at SMPSs
why there is 1 diode at the output of transformer, if it is outputting DC... the capacitor alone should be enough to filter the DC.. and if it is necessary for some reason, there should be 4 in the bridge format

I just understand after graduating Electrical Engineering 2 years ago. 😂
Thanks prof Mad🙏

The best prof explanation ever 1:44
Wow, it takes a lot of effort to animate this. Hands off bro
Very good video for very good understanding about mobile charger phones thank you
Excellent delivery. Prof Mad need to create more content.
Truly you are genius man
Nice explanation on mobile charger smps.
Thanks for watching
I like the information about the transistor.
welcome
A very good video with simple explaination ❤
Thank you! 😃
thankyou for such accurate video. 💯
thnaks alot for providing so much informion
smps always has my brain into thinking how a tiny ferrite transformer can provide such high currents.
same I used a
High frequency
Great video, one of the best on SMPS!
nice explanation with animation ❤❤❤
Very good understanding to viewers thnx
You are wonderful, thank.
Nice explanation
Very useful, thank you so much
There should be a resistor at the input to reduce the current, because that circuit will be overloaded with current which the diodes and transistors could not handle
Where should be exactly?
@@vitlevanskiy it should be at the input before the diodes
Many thanks it's an informative video
Nicely explained!👍
Thanks 🙂
Thanks for the wonderful explanation, prof. Still I am confused as to how capacitor C1 gets charged from the other side with DC current from S1 then turns on transistor T1 from the other side
very good explaination and video
Glad it was helpful!
please give details about construction of Resistance Temperature detector
do devices have this same process too for example, charging 5V but the device only need 3V, is it gonna overvolt charge or the device has regulator to step down V?
Cool
thanks make this video 😊
nice explanation

This capacitor is discharged while the transistor is open, isn't it?
Excellent
Wow 0:36
能不能讲有PFC的开关电源
👏👏👏👏
Je suis passionné par l'électronique mais j' ai besoin d'un encadrement svp
Awsome👍
I don't know much about electronics but really like this...Plz make a video on how to make a hand crank mobile charger.
sure.
@@Profmad Thank you so much.. I will be eagerly waiting for new video....
great

Some see the high frequency DC as AC, who is correct? Is it only AC if it oscillates around the 0 Volt axis?
hello can someone give me a digram for converting 220 v rms Ac to 5 dc
So AC > DC and then DC > DC

It's RC Bray, a super popular audio book narrator. AI is scary
Instead you shud say its Simple flipflop circut by two transistor to make it easier to understand that it makes PWM fast swiching at low cost😂
Nice +++
why there is 1 diode at the output of transformer, if it is outputting DC... the capacitor alone should be enough to filter the DC..
and if it is necessary for some reason, there should be 4 in the bridge format
Without the diode the capacitor would drain back into s2 between the cycles.
