Seeing concepts I struggled with for years explained in such an elegant manner as to be understood in a single video with maybe one or two re-watches is amazing. Your ability to strip complex topics down into their elementary components for explanation is unparalleled anywhere else.
Your illustrations are gems of youtube. These systems are very interesting and complex and to be shown intuitively is amazing. Did you as a child always loved electricity? I'm getting a degree in EE and your videos fueled my curiosity.
Thanks for the compliment and I am glad my videos fueled your curiosity. In reply to your question, I first got involved with the study of electricity when I was in high school.
Определённо уважение Евгению. Такие визуализации просто необходимы в образовании. К счастью, я в своё время быстро научился визуализировать для себя электричество =)
One is your explanation is so good, secondly you explain all the conditions which clears all kinds of doubts, thirdly your animations makes easier to understand the topics, all these qualities make you different from everyone else. . Thank you for your all videos. Please make a video for topic 'How electricity conducts according to band theory in conductors, how electrons move when electric field is applied, electrons move from valence band to conduction band and conduct current how to understand it in lattice'.
Thanks. It can be done with a microprocessor: Compare a square wave with a high frequency to our desired sine wave (with a lower frequency). At each moment in time, depending on which of these two waveforms is bigger, our switching waveform is either positive or negative.
Cool video. Question - the fact that in the last animation arrows grow bigger/smaller bit by bit, not just waiting for the full cycle (like in the first animation that showed it working with switching only when the arrow had maximum length), is by design and it shows the green voltage graph that is "closer to sinusoid"? I just want to make sure I understood it properly.
@@EugeneKhutoryansky Yes - but higher frequency has it's drawbacks as well. Hence why standard AC current is delivered in 50 or 60 Hz throughout the world. Some ships (Soviet Submarines for example) used 300 or 400 Hz. I do not remember all the pros and cons of high frequency, but there was a good video about it on RSD Academy. And making (especially in old times) elements that would switch very very fast would reduce their lifespans. One of the first grids was 133 Hz from memory.
The AC output would still be 60 Hz or 50 Hz. I was referring to the switching frequency. You can have a switching frequency in the kHz range, and still produce and output of 60 Hz or 50 Hz.
Switches do have heating and power loss when switching.. Because they are Power MOS or Solid State Relays so frequency does have some limitation on the efficiency, size or power. Plus some snubber circuits to protect the switches themselves. Not cheap. But many times you do not need a perfect sinusoidal wave, just a stable frequency It is not the same to run water pumps from a battery that an electric car. And for the russian submarines, I guess a 400Hz switching frequency noise may be easy to track if you know what you are looking for. EM noise is much worse at higher frequency.
@@EugeneKhutoryansky Of course. I simply started jumping to another topic that came to my mind. Apologies. I'm the kind of person that goes to Wikipedia to look for one thing and then spends 8 hours browsing through everything that piques my interest.
Beautiful animation video my mentor ! This was an example of brilliant circuit design and demonstration... Will you please make a video on tidal locking, tidal tearing up of a moon and tidal hill sphere... I still can't understand why the moons goes aways from us 4cm each day.... This is only possible if the moon's orbital velocity around the Earth keeps on increasing. But how the tidal forces from the earth are accelerating moon's orbital velocity? How the tidal forces can rip apart the moon if it tends to fall on earth? Are tidal forces same as gravitational force or it is something different? Is tidal force the reason of why galaxies are moving away from one another rather than dark energy?
Thanks for the compliment. If you want to use solar panels to generate power for an electric utility grid, then you need a 3 phase version of this circuit. Also, the inductor for each phase may be replaced with the primary coil of a transformer, with the load being on the secondary side of this 3 phase transformer. The transformer is needed to change the voltage, so that it matches the voltage of electric utility grid.
@@EugeneKhutoryansky Thanks for replying. After thinking about the video I now understand how an inverter can be bidirectional (to charge batteries from grid). Because there is nothing in the circuit that makes it one directional. Correct me if I am wrong. Btw, do all the PV inverters have transformers? I’ve heard there are inverters that are transformer-less. Probably to use less materials.

I was born in Kiev, but I moved to the United States when Ukraine was still a part of the Soviet Union. Also, I am not ethnically Ukrainian. This is because in the Soviet Union, Jews were considered a separate ethnic group, distinct from both Ukrainians and Russians.
On the screen we can see a Battery ... as a power source. Yep...! ... But as you are talking about DC source , ... You animate arrows * changing directions , what is not familiar with DC or battery source. But AC. .... I am confused ...now.
You are showing current flowing two directions through the battery. Shouldn't it be only one way and the switching of mosfet pairs give the two different circuits / directions independent of the battery?
The video shows it correctly. The inductor forces the current to momentarily charge the battery. Otherwise, either the current through the inductor would change instantaneously, or the current would flow through a mosfet when it is blocking.
There are many different types of transistors, and each type of transistor has its own symbol. I cover some of these in my video on transistors at czcams.com/video/Bine_PbyFSQ/video.html
I have taken too much time to find this equation. I am not able to publish it. But I want to take this equation to the world. Maybe this solves another problem of the universe Real Gravitational acceleration equation g=GM/(R²√(1+(GM/(RC²))²)) g=gravitational acceleration C=speed of light V = √(GM / ( R √( 1 + ( GM / (Rc²))² )) V = circular speed Without dark matter, it is almost matching the rotational speed of the real galaxy.
Hmm, I suspect this is how a music synthesizer creates an analog waveform using a digital tuning algorithm to switch the transistors. Or, maybe not. This is pure speculation. I need coffee. (:
Im surpised not a single person noticed the amination is wrong. Please do not think the current goes in both directions from the dc source, it is only meant to show how the output would act at the light bulp
The animation is correct, and this is why no one else complained about it. The current in an inductor can't change instantaneously. Therefore, when the transistors change their on / off status, the current must initially flow backwards into the DC source.
Ну и в чем смысл видео? Я все равно не понял почему транзисторы здесь переключаются. Евгений теряет хватку снимать действительно полезные, обьясняющие ролики 🙁
Стои́т там мультивибратор или, например, генератор на элементах "НЕ". А затворы транзисторов к нему подключены. Вот и переключаются. Важно, что при этом происходит, что и показано.
Thanks. I will add waveguides to my list of topics for future videos. Though, I already have a video on transmission lines (one type of waveguide) at czcams.com/video/ozeYaikI11g/video.html
@@EugeneKhutoryansky Oh I did see this video! I was hoping for one with more focus on waves! Like an EM waveguide. Showing the different modes and the physical significance of what a mode is and as such..

The Wedding March really made this material pop
(Partially) paying attention in Physics E&M in high school actually paid off. I knew what the inductor was, which helped me understand this video!
Universities need to start adopting this method of teaching. There would be much less confusion.
Beautiful and educational video as always!

Left me wondering how to give signals to transistors to act in the required manner.
Thanks. It can be done with a microprocessor: Compare a square wave with a high frequency to our desired sine wave (with a lower frequency). At each moment in time, depending on which of these two waveforms is bigger, our switching waveform is either positive or negative.
@@EugeneKhutoryansky I think it can also be done with only an oscillator.

In the real inverters big electrolytic capacitors placed after power supply. And low inductance busbar used to connected them to the transistors.

Every video a bangers but where are my sexy cgi math angels ?
How was the switching waveform developed? It looks a bit.... chaotic.

Don't forget the electrons. They jiggle and wiggle just to make YOUR day a bit brighter. Or rather the night...
Wow!!!!!!!
Love from Ukraine ! )
Thanks.
Now I understand what raising the switching frequency in a motherboard's BIOS does, and why it would increase stability.
Now I see all :0
OK I'll be that guy. What is the purpose of the tree log in the inductor? Is the from an Iron Oak?
How can we control the switching frequency ?
It can be done with a microprocessor.

I have taken too much time to find this equation. I am not able to publish it. But I want to take this equation to the world. Maybe this solves another problem of the universe
Real Gravitational acceleration equation
g=GM/(R²√(1+(GM/(RC²))²))
g=gravitational acceleration
C=speed of light
V = √(GM / ( R √( 1 + ( GM / (Rc²))² ))
V = circular speed
Without dark matter, it is almost matching the rotational speed of the real galaxy.
