Thanks professor! After learning a lot before doing my first transformer, still I have a question that is not answered. About the Ap value, the known parameters are L, Ipk, Irms,and n. Nevertheless, the number of turns is usually dependendent on the AL value of the core to select the appropiate n for the desired L...I think there's another way to know the number of turns for required application, but I did not figure out yet before selecting the type of core !!
This is a great video! thank you! Could you do another video outlining an example? i have been working on these equations, and it always seams like I'm off by a factor of 10.
Thank you, professor. I learn a lot thanks to your videos. At 8:34 you mentioned faraday's law and I wonder (theoretically and practically) how is it that the wire's geometry doesn't affect the EMF? according to Faraday's law, only three elements affect the EMF (n, Ae, B). So, if let's say the loop diameter is much much bigger than Ae, would the EMF stay the same?
Thanks so much professor. If I want to design multi legs (n legs) inverter (that I will mutual inductances between every nlegs, Can I use the last equation for Ap in the video? or there are a new approach for it. Thanks again for you
For a 6-layers 1.6mm 1oz (outer/inner) PCB an utilization faktor is as big as 0.67/ That's not a problem at all. ELP+I 43/10/28 N49 @1MHz can handle up to 1kWt, ELP+I 22/6/16 - up to 220Wt, and so on. It's enough space for a winding (and even a shielding). PS ER+ER 18/3/10 can handle 175Wt (with a shield layer; 1.6mm relatively cheap 6 layers 1oz PCB) and that's a remarkable number for a such small footprint IMHO
I really learned a lot from you professor 🙏🤞
Thanks
Thank you so much sir for reading our comments and responding on it
👍😊
Your videos are simply the best! Thank you prof.
😊
Thank you professor for the superb presentation. The material will be very handy.
Thanks for comment

I guess you aretalking about aninductor not transformer N= L*Imax/(Bmax*A)
Have you seen my RUclips videos on inductor design?
Outstanding.
Thanks
Thanks u sir

There are a number of videos on this subject in my RUclips channel e.g. ruclips.net/video/M3OEM6lnfRE/видео.html

Thnaks for comment. Yes, under the assumption that the magnetic flux is confined to Ae so encircling more air does not make a different.

Hi Sir! Is there a textbook source for this area product method?
Sorry I don't remember offhand
Creepage and Clearance is not clear in this video Sir. is it possible for you (if you have time) explain it more ?
Will try in future.Thanks
Great video. Did you recently become a lawyer? That was a very professional disclaimer at the start of the video! ;-)
I have heard that lawyers are making more money. So I gave it a try (-:
