- in this video number {269} Understanding Flyback Transformer to design SMPS. i explained what is flyback topology and how it works in buck or boost regulator technique
in this video i explained what is flyback transformer, how it work and how to design transformer
i am am going to calculate SMPS circuit using UC-3843. in this circuit UC1842 UC1843 UC1844 UC1845 C3842 UC3844 UC3845 MC38C42 MC38C43 MC38C44 MC38C45 MC18C42i can be used after making a slight change in VCC voltage. i will calculate all components in the UC3843 SMPS schematic, i distributed the power supply in blocks, so that it will become easy to understand. discussed how to draw a schematic circuit diagram of switch mode power supply and i explained practically. most of the smps designs buck converter, buck boost, forward, feed forward converter, half bridge full bridge converters are same just the switching topology differs. after watching this series of videos you will be able to:-
what are the ripples,
ripples in output,
ripples in rectifier,
ripples in output of power supply,
full wave rectifier output,
bridge rectifier,
output frequency of full wave rectifier
how to design calculate smps
how to understand smps design calculations for discontinuous flyback function of switch mode power supply, in this tutorial i draw the circuit diagram and placed components and made wiring of the components.
how to repair switch mode power supply when short circuit at input
how to calculate dc buss bar / rail and bulk / main dc / filter capacitor
hoe to select minimum maximum voltage for SMPS
how to design buck boost converter / half bridge / full bridge / forward / feed forward / zero volt switching ZVS / zero current switching ZCS / flyback converter

Hello Haseeb, I watched many of your SMPS reviews and you are very dedicated to your work. This is very pleasant to learn from you.
Would it be possible to describe the current sense circuit using the MOSFET current sense resistor and its priority over the Opto-coupler feedback circuit.
Is it this circuit that shuts the UC-1842 when there is a short on the secondary side?
I am busy my store my work that’s why I am missing your video sorry brother I like your video I like your work that’s why I am watching your full video go and check your computer thanks🙏😄
I so much appreciate your effort to impact your knowledge to us. Does it mean that the secondary winding will be in opposite in direction
وعليكم السلام زرحمة الله وبركاته
شكرا على الغيديو المفيد👍🌺
Super 👍 merci
Thanks for sharing my bro
my God this is outstanding...Best of luck for yjur future videos💕💕💕
Your presentation is always superb. Thanks for sharing
Great work.... I love the explanation..
it is my pleasure
Nice
Good inventing my friend (I'm Antonio ) I'm from Brazil I like very much of videos (please do make a video about snubber) more a thing I am learning English with yours videos.
Thank you my friend.
Goood job 😊👍👍👍
Insaallah Allah save you for Rıdaullah. Thank you
جزاک اللہ خیرا و احسن الجزا
Great Video!! Like 103
شرح جميل وانت شخص متمكن من عملك ومبدع
thanks a lot dear brother
does the flyback transformer reduces the input volatge like a normal transformer (based on the primary and secondary windings), or the voltage on the secondary is changed by changing the duty cycle in activating the primary.
as it is a regulator, so its output is regulated in both cases. either the input voltage change OR the load is increased in output. in both cases its output is regulated by changing the duty cycle by the PWM controller ic, which is working at some specific frequency.
if the dc rail / input voltage will decrease, OR the load increase
the pwm controller will increase switch ON time to increase the primary current to compensate the drop.
Have A Nice Day Jumma mubarak Ho My Brother
Haseeb Bhai. Adab from India. Love your work. I have a question. In your example the required output is 10 Watt. But you are selecting a core of 100 Watt. Why is this needed.
Make a video on transformers polarity? E.g how to check polarities?
Thank you for sharing hope we always communicate 👈👀👈👈👈👈👈
It's really a great experience learning from your videos. You are a genius in your field.
Can you please make a video on design of smps transformer of an half bridge llc converter topology for high powers?
Thanks
thank you master
Sir, Thank you very much again. I've noticed in your video about flyback transformer calculations that you selected a duty cicle D = .48, before to calculate it, I mean, you assumed it, but can we select an arbitrary value of D or should we calculate it and then have the calculated value? Thanks in advance and much appreciation for taking your time to share your knowledge, God will reward you with oveflowing.
I would like you to answer my question, should I a take a random value of D or should I calculate it, please? Help me to kill My doubts about this topic.
while calculating flyback topology, we have to divide a switching cycle into 2 portions
ON time & OFF TIME
during ON time, the magnetic energy is stored in primary winding
in OFF time the stored energy is transferred into the secondary windings
(this is basic concept of flyback, that there is no output in secondary in Pulse ON time)
so to make it DCM flyback , we have to allow some portion of ON time and OFF time as dWell time. this time is dedicated to zero the primary current (so the there should no resonant current in primary winding before new pulse which is expected in next moment) this is called discontinuous current mode flyback, to achieve DCM function we must have to slect duty cycle less than 50% and 2% out of 50% should be allowed to discharge the primary current
to make it CCM, the duty cycle may be adjust above 50% so that the next cycle will start switching when there is current present in primary *it is called CCM*
We should calculate it
Duty cycle with no load
Dmax with full load
Duty cycle with VDCmin
Duty cycle with VDCmax
Thanks,
Sir please complete this SMPS calculation
yes dear. I have to complete it
Assalamu alaikum wa rahmatuhu,
Excuse me please, Which camera u used, I saw that's focus mode too slow, maybe setting issues
Thank you

Salam, kya 12v inverter ke transfomer ki winding change kar ke us ko 48v inverter ke liye banaya ja sakta hai.
Dear sir how to convert DC of transformer output?
using rectifier and output filter and dc capacitor
I have an inverter 12v to 220v modified sine wave with 100Hz , voltage is ok , could you please give me a hint to solve this problem.
I do not see the video where he is calculating the primary current and RMS current in the primary. Does anyone has that video. If so please share with me. Thank You
Good video, but is there a dinosaur in your lab?..lol.
it sounds like tyrannosaurus rex is there..
Excellent presentation you are doing great job man highly appritiatv by new frnd
Hello Sir, may you pls help to understand how snubbwe ckt. Design in smps. Pls also make me understand how to learn desig the ckt. I am confused in the little ckt. What will happen next.
please check video number 284 and 510 in my channel
Sir where is video #268
video 268 is available on my channel for dwalt battery charger circuit
