auxiliary voltage are calculated based on the PWM IC's UVLO upper limit (Overload Protection) voltage value at the maximum power output of the converter for example the smps is designed to produce 20 watt output. at that point the auc winding must provide voltage equal to or slightly above than the IC's VCC upper limit
Please how to calculate the air gap in flyback topology and how to introduce the air gap on the transformer because all the flyback transformer I see is gum together with gum no space between the two core legs
hello again I ask you do you know how to calculate WaAc of a UI and UU core (type of high voltage tv flyback for example) I was seeing that the section of the nucleus varies according to the dimensions of the same nucleus. If you help me I appreciate it, thank you.
Hello :) I have noticed that all presented methods choose different kind of core. I mean that for this application we cannot to mark one type of core out. Why is there difference between these methods?
yes dear, there are various approaches. discussed WaAp method that is fourth power and i discussed core Geometry (Kg method) that is fifth power please check video number 430 that is specially for fourth power calculation
Great job sir! Little guidance needed how one can buy EE core and Bobin from Pakistan any online website in Pakistan? I try multiple shops in Karachi but failed buy EE cores as required for my project for example I need only EE-19 core where can I order to buy this one. Thanks
Sir I like your video very much. I have dought in Isolated DC to DC converter for 36-72 v input and 12v@10A and it's transformer design. can you please help in design isolated DC to DC converter and transform type also
Sir plz thoda easy banake do aapke video main puri dekhata hu pr kahi kahi pr confuse ho jata hu Jaise ki mere pass bohat sare ferrite ki bohat core hai but konsi core kitna output deti pata nahi. Our jo aapke core size hai usme se konsi core mere pass hai samaj me nahi aata . To core konsi hai kaise samje plz isape ek video bana de
Assalamualaikum Mashallah very useful and helpful video Thanks for sharing wonderful video. one request how to calculate ETD core Ce.Ex-ETD 60 or ETD59 (Round center pool)

Walekum Salam sir
You are a great teacher and your English is excellent. I can't speak fluent English like you . You are awesome 😁🙂🇬🇧🇬🇧
Well explained. Good teaching
Excellent work , too much hard work and a best method to represent the topics.
Excellent way to learn
Behtareen sharing, a very detailed oriented explaination always, just like you teaching to beginners. Keep up the good work bro. Jazak Allah.
Thanks again for your efforts
Mashallah very useful and helpful video
Thanks for sharing wonderful video with us
Hi Sir, where did you get this power handling chart.
Hi Sir, In the 2nd method WaAC, Could you please explain what is the winding area (WA) value used to select the core.
Hello my friend have a nice day
Great video and thanks for sharing
Still watching very informative
thank you. what is the reference document you use?
Transformer and Inductor Design Handbook by Colonel Wm. T. McLyman
also pressman is same
U really did very hard work to the vedio ... Described well
Hi. thank u. awesome video.
where can I find the documents?
You way of explanation is so amazing as well as impressive ..
May God give you more & more success 🙏💐
What a fantastic vidio. Really enjoyed watching your vidio. Hope you have a great weekend. Many thanks from Chris 👍
Merci 👍
Thanks for sharing
how are you calculating auxiliary winding voltage and current? In the video, you assumed that.
auxiliary voltage are calculated based on the PWM IC's UVLO upper limit (Overload Protection) voltage value at the maximum power output of the converter
for example the smps is designed to produce 20 watt output. at that point the auc winding must provide voltage equal to or slightly above than the IC's VCC upper limit
@@HaseebElectronics Thank you so much for your generous reply.
@@HaseebElectronicsbut sir what about current through auxillary winding ,why you have taken 0.5.
Sir 6.19 min How we can select Wa parameter .. Please advice me
Please how to calculate the air gap in flyback topology and how to introduce the air gap on the transformer because all the flyback transformer I see is gum together with gum no space between the two core legs
very informativesir
best regards
hello please share charts i cant find them!
بالتوفيق يارب احسنت👍↩↩
مجهود رائع فيديو مفيد ⚘👍🌺
Sir Iam unable to find the next video #271 can you please help.
I’m design same calculations for 12V 2A can it possible?? & How select auxiliary voltage & current 🤔
I am watching full video go and check your computer thanks God bless you brother😎💟
Excellent, very useful tutorial n explained nicely asusual.
Big Like 👍
I can't find the following video.
Can you explain the working principle with circuit diagram of Back-UPS 650 APC model: BX650LI-MS ?
i noted it. i will arrange it and will try to explain it soon

Bmax is it in gauss or in Tesla
Excellent work you doing hard work allah barkat de Ameen 👍👍
Walikum Salaam Janab bhai Saab & Good Day
Nice video 👍👍👍👍

W salam nice share i did waiting ur new upload always thanks
Using the AP method how to know the primary and secondary winding area
Sir I like your video very much.
I have dought in Isolated DC to DC converter for 36-72 v input and 12v@10A and it's transformer design.
can you please help in design isolated DC to DC converter and transform type also
Salm bhaiiiiiii ,Kia haal h lk 25 k sath MashaAllah bht achi informative video share ki h Apne fuly watch Allah bless you
What is ,Bmax???
it is maximum flax density
Nice 👍 to watch it
ماشاء الله Keep it Up
Haseeb bahi how are you
Gooood 😊😊👍👍
Please share all paper of these calculations in PDF format. Thanks.
Sir next video kaun sa number hai
Mashallah Bahut khoob
Can u send this charts
please check video description
there is link
Thanks for your tutorial but you didn't use kg method
Waalaikumsalam
Barokallah
thanks again.must i go read all in the internet.
Sir... can you upload this hand written notes in pdf form..
Sir plz thoda easy banake do aapke video main puri dekhata hu pr kahi kahi pr confuse ho jata hu
Jaise ki mere pass bohat sare ferrite ki bohat core hai but konsi core kitna output deti pata nahi. Our jo aapke core size hai usme se konsi core mere pass hai samaj me nahi aata . To core konsi hai kaise samje plz isape ek video bana de

@@HaseebElectronics Assalamualaikum thanks for your reply.
Dear sir please share core chart
Salam walekum 💐💐
Thank.but in this video no one cant know any things.every things are intersected.
thanks for your trying to teach.this video is so confusing.all things is spagetti.
