Does the actual position of the wires make any difference to the performance of the transformer? I mean, for example, conventionally you would have the primary winding at one side and the secondary (or more) winding at other. Would it matter, for example if both primary and secondary windings were wound together in a random higgeldy-piggeldy fashion? Would this scheme have any adverse effects, or perhaps could it even be desirable? Thank you Prof. I find your video explanations not only extremely informative, but curiously very satisfying and of the utmost quality, (the technical details rather than the audio-video which is also v. good) Thanks again from Brixton, London UK.

15:00 I tried to use that formula with my transformer: 50mm2, 0.04T, 1MHz, 200V and got 50 turns, which is a nonsense, because my trans uses 7 turns and 0.2mm gap. May be a square root is missed in the formula
I find it completely counterintuitive that we should be able to find out the number of turns per volt (@15:13) without knowing anything about the relative permeability of the core other than it is high enough to guide the flux into the core's area. Am I missing something here? Wouldn't low permeability materials yield very high magnetizing current? If this sort of works itself out, can someone point me to a resource that explains what is going on in low perm. cases?
(9:50) - Please, does the "core cross-sectional area" include the outer "ring" or does it refer just to the central "pillar" ? Do you understand what I am trying to ask ? I know I am not too good at trying to describe what I mean here but if I confuse you, I will try again. >
Hello, Thanks for the lesson. I have been doing it differently but my windings get very hot in operation. I suspect I need to use higher gauges. My question now is What variable "d" is ? n Vin d = Vo Many thanks. Jose in Mex.
Hello sir what is difference between coupled inductors and transformer. Specifically why do we need to store energy in core in form of field in case of coupled inductors rather then transmitting as transformer??
2 questions. I have looked at a few abstracts. On some they use the reflected voltage to calculate n and on others they use the vin over out. Which is correct? Also if Bmax is specified by the core and it is not exceeded in the calculations then why do we need the air gap. I understand that the gap changes the slope of the BH curve but is it required in all cases. Thank you
What is the Ac is it in mm2 or cm2 or m2? Vin=2Np*Ac*Bm*Fs Np in turns, Bm in Tesla, Fs in hertz. 1/second. i think its in m2 because 1T=Volt.s/m2. So if i have a 1cm2 cross section area of ferrite. And if i swich it 50khz.. i should wind 160 turns primary for 315-320 volts ac mains. High Frequency decreases transformer size very well.

Yes, jarnega.

if primary and secondary wounded together then you eliminate leakage flux
So nice the world's best

Thank you sir for your brief explanation. Still have the doubt about demagnetizing current voltage wire

Thanks you sir
I am a magnetic designer and I follow the kg method
Once explain it sir
Thank you sir it is helpful for me .
Where is an experimental setup to show the behavior of the designed cores.?
(9:50) - Please, does the "core cross-sectional area" include the outer "ring" or does it refer just to the central "pillar" ?
Do you understand what I am trying to ask ?
I know I am not too good at trying to describe what I mean here but if I confuse you, I will try again.

Just the center part of the transformer. The pillars you are talking about are normally half the core cross-section area each.
Hello, Thanks for the lesson.
I have been doing it differently but my windings get very hot in operation.
I suspect I need to use higher gauges.
My question now is What variable "d" is ?
n Vin d = Vo
Many thanks. Jose in Mex.
'd' is the duty cycle = time on / switching period
how can we desing or select the transformer if the load is only known of commercial building
you said data sheet to find the size of the core, so from where can I get this data sheet pls?
Sub titles running on down screen hides the content behind. It's panful.
sir Please 🙏 make about design of all winding design
The formula for calculating the Np gives irrelevant results....
Hello sir what is difference between coupled inductors and transformer. Specifically why do we need to store energy in core in form of field in case of coupled inductors rather then transmitting as transformer??
A transformer works in essence as a mutual inductor or a coupled inductor.
