Super helpful video, very well explained. Thank you!

Best explanation I have seen. Excellent and thanks!

Very good explanation! Thank you for your effort. By the way I saw your videos on Odysee. I came here because videos were buffering for a loooooooong time. But it is so much easier to find relative content on that platform.

I am a total lateral entrant in to electronics and wow this is great stuff I even dare to say that I get it. Thank you so much!!!

Thank you so much. One of the most helpful and effective video I have ever watched on Yotube. Much obliged.

Excelente explicación sobre el tema, muchas gracias. Saludos desde Argentina!

Congratulations on the nice volume level - it matches the quality and clarity of the video, and the clean/organized work bench. Far too many otherwise interesting videos relied on the cheap microphone of their camera making the video unhearable/unwatchable. I wish every author had your attention to detail in this regard!

When I first learned that a magnetic core was added to transformers to get a larger magnetic field for less primary current (less primary current compared to how much current required with air core for the same magnetic field coupling), I thought "okay, the core magnetizes and less primary current is needed to get a bigger magnetic field coupled to the secondary" But the larger magnetic field means higher current in the secondary since current increases with magnetic field intensity. So it seemed odd "we use the core to boost lower current in the primary to get a higher magnetic coupling to the secondary, but when the secondary current really takes off - when the core saturates - that's somehow bad." Faraday's law, induced voltage directly depends (varies directly with) magnetic flux created by the primary, and the core boosts the magnetic flux. Obviously, the non-linearity when the core saturates and the secondary current goes non-linear is a factor .

Thank you from the other half of the world

*In this context I have a question regarding flyback transformers:* Instead of a single coupled inductor (gapped core) with a high windings ratio, would it make sense to instead use a low windings ratio coupled inductor (to deal with inrush currents and core saturation) and connect it in series with a transformer (non-gapped, toroid) to do the majority of voltage up-stepping (=at a higher efficiency than a gapped core)?

Greaaaaaaaat

How does this change when there is a load on the secondary?

Sir, could u tell me whether transformer always goes to saturation

hi, at 15:10 you say transformer primary is 20 ohms and you calculate 6A max current but scope shows 7A, I think the mistake was that 6A is maximum RMS current and you are measuring maximum peak current. So at 120V RMS, you have about 170V peak voltage and at 20.5 ohms (primary+shunt) that could produce max peak current of 8.3A.

so what to do... between switch and fuse,,, never to be answered

Max current indicate to voltage cross zero sinusoidal 120V/60Hz and blow fuse very hard to set in this point Fuse chose to transformer slow blow and nominal current for this power rating Outerwise don't blow fuse set high current mesurent this point in this video

This explains why microwave transformers draw so many amps from mains lol
