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
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🙏

smps always has my brain into thinking how a tiny ferrite transformer can provide such high currents.
same I used a

Excellent delivery. Prof Mad need to create more content.
The best prof explanation ever 1:44
I like the information about the transistor.
welcome
Nice explanation on mobile charger smps.
Thanks for watching
A very good video with simple explaination ❤
Thank you! 😃
thankyou for such accurate video. 💯
Great video, one of the best on SMPS!
Excellent

Very good understanding to viewers thnx
nice explanation with animation ❤❤❤
Wow 0:36
You are wonderful, thank.
Very useful, thank you so much
Many thanks it's an informative video
very good explaination and video
Glad it was helpful!
nice explanation
Nicely explained!👍
Thanks 🙂

please give details about construction of Resistance Temperature detector
Some see the high frequency DC as AC, who is correct? Is it only AC if it oscillates around the 0 Volt axis?
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....

It's RC Bray, a super popular audio book narrator. AI is scary
Awsome👍
great

hello can someone give me a digram for converting 220 v rms Ac to 5 dc
Nice +++
👏👏👏👏
So AC > DC and then DC > DC
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.
