Prof, could you take a look at a question someone asked on the riddle, about open circuiting one leg of the parallel MMF situation? This video cleared up a lot, thank you again, but that situation remains unintuitive to me. Based on another comment about parallel MMFs reflecting to input in series, one open circuit must stop current in all branches. I now think it must relate to 9:20 here about the pure inductor case, that only Lm would have current and none flows in the loads.
@@electrowizard2000 Flux will not enter practically into the loaded winding and will be diverted to the leg with the open winding. So you end up with an inductor from input side, practically no output voltage at the loaded winding and the voltage of the open winding is now like a 1:1 transformer , in this case 10V.
This is exactly the knowledge i need more understanding of. I stay watching this videolesson, but pc simulations i am not used to the same way as to a working circuit or scopepictures. It is not the easiest way for me to get that intuitive insight. But it doesnot have to be easy and all the insights are presented in this lesson so i will watch and learn until i get that inner picture totally clear. But i still have some childish ideas to which i mis the why. Or why not of course. Things as why should the saturation problem in a dc inductor not simply cannot be helped by a permanent magnet in the core? One direction should saturate earlier so the other direction has to have more room till saturation? But thats one question i still have, while some others are finally see trough since this lesson so i can never mis one lesson of yours because i cannot learn that much and that easy to follow knowledge on any other way than with these unique way of explaining that most interesting items from the whole electronics knowledge. Thanks for particulary this videolesson more than i know how to say.
Nicely explained. I use your videos to relearn my lost knowledge. Thanks for taking the time to make them. Best wishes from Norway.
👍and returned wishes from Israel.
Another excellent tutorial on the inner working of transformers.
Thanks for the kind comment.

I thought I have answered it. If one leg is shorted flux will not enter it due to Lenz's Law. So now there is a 1:1 transformer.
@sambenyaakov sorry the modified question was if we *open* one of the three legs, not your original question if it was shorted.

Would you please introduce a source to model parasitic capacitances of a high frequency high voltage transformers through measurement?
Thanks
I am not sure I follow you.
@ thank you sir

Thanks for kind note and for sharing.
I think you accidentally drawn a reversed second winding direction in the first schematic of the video.
Thanks for pointing this out.
