For isolation, some of the high voltage semiconductor components use optically triggered gates with fiber optics leading to the control circuits. But I bet they still go bang in a very expensive way.
oh hey Clive,what a brilliant way of using fiber.
@@ppsarrakis Almost every substation in existence uses Fiber in some way
You still need power to the gate of the semiconductor device don't you? Even if it's optically triggered?

One other advantage of HVDC for grid interconnects is that they also function as an asynchronous tie allowing the interconnection of two AC grids that would otherwise be incompatible because they operate at different frequencies, this is particularly important for grids that would otherwise be isolated due to the frequency mismatch with all of their neighbours. With the move towards more renewable generation it is only becoming more important for grids to work together as different grids have access to different natural resources for power generation and variety helps to balance out the individual fluctuations.
Oh that’s great I never thought of that 🤭
That's exactly what happens in Itaipu. Their 10 Paraguay-side generators run in 50Hz and export 80% of their energy to Brazil in HVDC, then it is converted to 60Hz
But it does not matter? You can still convert AC to AC
@@Aguy644to a different voltage yes, very easily. But if you want to, for example, convert from 500KV 50Hz to 220KV 60Hz you need to convert to DC first. Otherwise you will get 220KV 50Hz, and what will happen is the same as in 5:49
5:50 :You know it's going to be a nasty shock when even Mehdi braces for impact.

Ok, Johnny !
Here is your job: you switch DC back into AC. It’s easy, really, but if you don’t synchronise your legs with the mains everything will explode.
I worked for a power company that utilizes a 850 mile DC line from Washington to California. The DC POWER moves at the speed of light (in metal - weird but true), but the individual electrons move very slowly. This DC line is about 50 years old. An individual electron that started at the north end of the line won't reach the end of the line for many more years (75 mile trip)!
Yeah because drift velocity of electron is pretty small

Well, in europe the frequency is 50hz so I can pay even less money to the underpaid workers.
It's free real estate
But 50 hz messes with older electronics.
Ever hear of sluggish sonic games?
@@spidercubed9718 Some equipment uses the mains frequency to drive their clock (eg: old consoles, and even some modern electric clocks), it is actually quite a sensible source for a cheap, stable, known frequency ... until you ship your product to a country running at a different mains frequency, then your electric clock (or CPU clock) runs at a division/multiple of *that* mains frequency. So Sonic, programmed to run at 60 FPS (footfalls per second) in N-America/Japan, can now only run his little blue legs at 50 FPS* in the rest of the world. Luckily, the rest of the game is equally slowed down to match, so he doesn't notice. But the player does notice, as most people's brains aren't clocked to local mains frequency, (ElectroBOOM being the exception: since he is so often wired into the mains, it makes sense in his case.).
* the relation to *real* FPS in terms of TV Frames Per Second is because analog TVs would sync. to the mains frequency, which is why it was *very* important for the power company to keep the frequency *very* stable (and synced at least across each broadcast region, as the transmitter also had to sync to the mains frequency so the TVs could receive its picture), which takes us back around to why the mains frequency was such a reliable source of cheap stable frequency ready to be used by console makers who didn't initially think of exporting their products globally then hit little frequency snags when they eventually did.
@@vikiai4241 Love your explanations xD
Iam from Europe to but we got 50/60 hz
I live on a small island and the power is pretty "dirty." Our stove clock gains minutes every few days as a result, it's crazy.

I work on industrial sized UPS units, it was really fun watching this video knowing some of the things that were coming with regards to AC > DC > AC conversion! I should link this to some of my new recruits to explain why we have an input transformer with a delta and a wye secondary to create a 12 pulse rectifier, you explain it so much better than I ever did.
12:52 Edison flew out of the window lol
The evolution of HVDC conversion technologies has been from mercury-arc valves to thyristors to insulated-gate bipolar transistors in the newest installations.
Turning it on and off at the rate of the AC grid works, but needs a lot of filtering to remove harmonics. Newer installations use multi-level converters which do a better job of approximating the AC sine-wave and thus need less filtering, and which in turn can take a big bite out of the cost of an installation.

"sign waves are coming from city and square waves are coming from inverter, they are not in same shape and frequencies are slightly different"
"To connect them, they must be at same shape ,same frequency,same phase,same voltage level ,same background ,same ethnicity and graduated from the same school"
Underrated
👍🤣🤣🤣
While applauding, a little correction: sine wave, not sign :)
And there is actually one thing to elaborate on the Mehdi's speech too, the shown inverter output is called "modified sinewave", which is a fancy name for that impure square wave, doped with deadtime between semicycles and voltage set near-peak value of the equal sinewave.
There is also another, rather a glib inaccuracy in the video, using the MWO transformer in demonstration. It is bad for such, because they are famous for actually consuming whole lot of real power when idling. That's because they are not designed to ever idle - they always have the magnetron hard-wired in their secondaries. Thus they are designed with as little turns in primary as possible without the core saturating at the working voltage *with the voltage drop caused by the constant load*. Therefore, when they are "misused" without the magnetron-sized load, primary has the full mains voltage without the drop by the load, and the core goes into saturation and high real power gets turned into heat on primary.
sign wave lol
Cleverness is knowing what people mean without acting like a fukin spelling checking English teacher 😅😅😅😅
2:45 The osciloscope shows some noise every time Mehdi leans over it. Why is that?
I think my body is coupling the switching noise from the power supply to the scope.

I had to watch one of those compilation videos the other day of you saying FULL BRIDGE RECTIFIER!!! then I watch this today and I get exactly what I wanted.
I love how educational and entertaining your videos are and also gives me anxiety at the same time.
I work for a utility yet this made me understand the conversion process simply and clearly. Interestingly, we use DC conversion stations where we connect to some other grids. By converting to DC and back to AC we are able to handle frequency irregularities (that come from a utility that uses some of the longest HVDC power lines on the continent).
As a second year Electrical Engineering student, I'm so glad to have come across your channel, purely by accident. The amount of work you put into your videos is clearly evident, and it feels just like home. Keep up the good work :)

@@Anomoomin or, for a lifetime of inefficiency and shame, a voltage regulator would work... unless, y'know... tubes.
but switches will be destroyed, no null point to help break the circuit.
.... If you really want, you can build a distribution level rectifier by taking the mains, converting it down to a highly regulated 12V, then using only high quality car audio equipment. Course then you'll have noise from the circuits that get it back to AC again.

As an engineer working with HVDC systems this was great to watch. It sure is an interesting technology.
Hi! Congrats on the video and your channel!
I'm a power systems engineer in Brazil and allow me rectify some inaccuracies about HVDC (in Brazil there are 5 HVDC lines 2550+ km).
The correct name is 'DC links' because it controls the power flow between two independent AC systems.
For instance a hydro power plant and the national grid or two countries one 60Hz and the other 50Hz.
We don't care about the wave form, we want to control the power flow over the line. To do that we control the SCR trigger. The HVDC doesn't work as a gigantic UPS.
The terms 'rectifier' and 'inverter' are used when you have a hydro power plant because they indicate that the power is flowing from the rectifier (plant side) to the inverter (consumer side). It make sense because the power always flow from the plant to the consumer. But if you consider a link between two countries the power flow direction can be either way.
Therefore, Edson is still wrong ;-)
Cheers
Thanks for your clarifications Ricardo! It's always good to hear some input from people in the field.
Not to mention the fact that Edison is also wrong because AC-motors are usually more efficient and have less maintenance than DC motors.
This is not that big of an issue in most households right now, but it might become a huge problem is heat-pumps and bigger airconditioners start becoming more commonplace due to climate change and rising power-bills. The mechanical components are usually simply the biggest power-consumers in just about every system.
Ei Ricardo! Sou estudante de engenharia elétrica, e me interesso pela área de transmissão.
Uma dúvida básica que tenho sobre a transmissão DC: No controle da transmissão AC deseja-se uma maior ou menor corrente nas linhas devido a variações de demanda e também atenuação de efeitos capacitivos das mesmas. Para estes casos, basta a utilização de transformadores com mudança de TAP para controle de tensão. No DC, embora os efeitos capacitivos não existam, a quantidade de corrente devido a demanda ainda precisa ser controlada. Como é feito o controle de corrente nos cabos, de forma a garantir o fluxo de potência necessário?
Felipe Magalhães o fluxo de potência no link DC é controlado pelo ângulo de disparo dos tiristores nas duas extremidades da linha, mas acho que a sua pergunta é mais ampla. Em todo sistema de potência existe uma 'barra swing' que absorve as variações de carga de forma a sempre manter a geração igual ao consumo, afinal não há como estocar energia elétrica. Podemos estocar a água dos reservatórios.
Normalmente a barra swing é uma grande hidroelétrica que fica configurada para operar 'livremente' enquanto as outras geradoras ficam modo PQ constantes, ou seja ficam gerando sempre a mesma potência ativa e reativa.
Espero ter respondido sua dúvida
@@FayettiSiqueira respondeu sim! Muito obrigado 🙂
wont you get square wave if simple diode method is used, in sine wave inverter we use IGBT with PWM signal to make Pure sine wave(How would one use filter to make sine wave from square ) . How does that phase shift transformer works & would it be possible to phase shift the generator it self as many power plants have more that 1 generator some even have 3 units which could allow 9 phase and reduce the size of capacitor needed to reduce ripple in the DC .
Diodes aren't voltage limiters or filters. They are on/off valves similar to a one-way check valve. Whatever the voltage is doing while the diode is on, aka forward bias, will be seen on the output. If the input happens to be a sine wave, you will see the peak of that same sine wave on the output of the diode while it is in forward bias.

Hi, Mehdi! Related to the HVDC topic, there's one kind of measuring device used to measure the DC current on HVDC circuits, called DCCT, or direct-current current transformer (that is not exactly a transformer in the proper way). It's also refered as Hall Effect CT or Zero-Flux CT.
It would nice if you ever develope a video about it!
From a huge fan of your work and sense of humor, I wish you the best.

You probably hear this all the time (like once every 6 months) but you are one of the funniest and educating people I've ever seen :) thank you for all the videos and if you ever come to Holland.. well.. enjoy.
I did my MSEE project on researching methods of measuring ions generated by HVDC power lines back in the '80's. I haven't thought much about them since then :-) But I LOVED your video, you are hilarious!
A long time ago here in Sweden they tried to distribute domestic DC in a few large cities (or perhaps just Stockhom?) but since DC is really prone to jump in order to create shorter paths - and the gas lines were running next to the DC lines, the results were less than impressive when enough jumps from DC lines to gas lines had eaten small holes in the gas lines and things started going boom a bit here and there...
Lesson learned - DC ain't the same as AC - especially when it can jump over to other metal parts trying to find a shorter path ;)
Wrong, it's how high the voltage is that is the factor that causes jumping or arcing.
AC crosses zero voltage 60 times a second which will break arcs, while DC does not. The fact that it's DC doesn't cause arcing, but it is far more damaging when it does.
I just loved the "things started to go boom here and there" part.
I keep showing my classmates your videos and sometimes they either laugh uncontrollably or, the entire classroom hates me
I wonder which one this will be
Informative and entertaining thanks
