I wish we had benefited from such audio visual aids when I did electrical engineering (late 60s). At the time, we were only told the _outcomes_ and then had to learn the mathematical theory by rote. I don't think a single student graduated with a true understanding about the ionic or molecular issues. At the time, thyristors were described by or lecturers as a mysterious semiconductor that could switch large currents - and that was about it. They didn't even refer to Shockley as the progenitor. Many applications, at the time were using huge thyratrons - some were water cooled. When they burst, the fun really started.
@@facitenonvictimarum174 Shockley was indeed a racist. He was a big proponent of eugenics. He not only believed blacks were incapable of being as intelligent as whites, but that he and other "geniuses" had superior genes to the general populace and openly talked about giving his semen to a sperm bank developed for people with high IQ. As an EE student, I respect him for his discoveries, but the dude was from a different time and stuck in his beliefs, that's for sure.
I designed and built a lot of gear in the 70s using SCRs and Triacs in disco lighting control gear. I knew how they behaved very well but never really knew the actual way they operated. I see now how the SCR anyway worked.
An improvement would have been to explain the difference between a Thyristor (SCR or Silicon Controlled Rectifier) and a TRIAC. A TRIAC is basically two SCRs in antiparallel - so it is possible to control both half waves of AC power at the same time. Thyristors are utilised in converting AC to DC and viceversa. It is possible to build thyristors with thousands Volts Vr, and ten thousands Ampere of controllable current. This is not feasible with transistors. Thyristors are also widely utilised in railroad rolling stock. Thank you for the video...

Thanks for the explanation LE, I never heard of a thyristor before and it was really as clear as mud to me how it works and why but, just like all things electronic it's a massive mystery.
Well it explained better than all my high school textbooks, although I understand majority part but seeing this made me understand completley. Before I had to reply on memorizing but now that I understand its has become easy to memorize.
As always, another excellent video from this channel. Just one precision: even when a diode or a thyristor is in high resistance mode, they are "working". In other words, "being working" is not synonymous with "being conducting current".
These type of videos compansates the huge gap of efficiency between theories lectured in the class and the understanding of the delivered lecture by the learner
Thank you for this awesome video. This is the very first time I understood this whole issue. Either one or two barries layers. And the external voltage source acts as a trigger to start conduction. Wow, now I just have to figure out what the "Nullkippspannung" is and then off I go.
its one big multi-layer diode. so they just use it in a big rectifier array to convert ac to dc. single layer diodes would burn out if you reversed the current at that high of voltage. so adding more layers significantly increases the reverse current stopping capacity. but because of the extra layers; you have to pre-charge each extra layer in order for it allow current flow in forward direction. you could do the same by putting lots of single layer diodes in paralleled but in order to split enough voltage off not to burn them all out you would have to use way too many diodes to be economical. this is just a way of making super high voltage diodes with much less silicon. further more when the current is going forward the thyrister works like a closed switch. but when its going backwards it acts like a big capacitor. the LC inductor is not to help turn off the thyrister so much is its to help ease the massive voltage spikes you would get when the current reverses again and that capaciter turns back onto a switch with extra voltage pushing the capacitor charge out. the result is that a thyrister rectifier sends ultra high voltage DC pulses down the wire instead of AC or constant DC. the high voltage pulses have the same long distance transmision properties as AC but without the current ever fully reversing, thus causing flux in the wire to reverse, thus cause the wire to expand and contract and generate lots of heat and lose energy. also the same way that most communication lines work. DC pulses for long distance... with diferential signals to detect voltage errors.
The concept of thyristor is a lot harder for me in the textbooks. This made it a little more intuitive but full insight of thyristor is still unclear or missing.
Big fan of yours...I LIKE YOUR 3D MODEL...Because it helps me so much...I request you to make more Video at electronics...your follower and subscriber will increase...
Very well explained and shown! (But I was just wondering if those circuits shown will run on teeny tiny Eveready Batteries as well as your Duracell. I have all these semi-microscopic batteries Iaying around doing nothing ... )
I like how they correctly show the flow of electrons through a battery. Most people think the electrons flow from + to -, but the opposite is actually true.

Two SCRs can be connected to form a high current triac, because single constructed triacs are limited in power.

I"ve seen a lot of videos try to explain transistors, this was the best one I've ever seen.
Amazing animations, they make these concepts so much easier to comprehend
Wow, so easily explained, one of the best videos you ever see about thyristor, thanks for amazing work
Wow the animation on this was great. Really helpful for visualizing electron flow through a semi conductor.
I am thyristy for knowledge. Great video 👌
me too but the large breasted woman at the beginning is quite distracting
I just want to see electric cars with graphene batteries, is that too much to ask?

Thanks for your video.
Great video! Just one suggestion: I don't understand how the described device turns A.C. to D.C. and vice versa. Thanks for the video!
it is because , during reverse bias no electrons flow thus converting it into unidirectional flow or DC
Bud Step it's just working as a diode in a special manner
its one big multi-layer diode. so they just use it in a big rectifier array to convert ac to dc. single layer diodes would burn out if you reversed the current at that high of voltage. so adding more layers significantly increases the reverse current stopping capacity. but because of the extra layers; you have to pre-charge each extra layer in order for it allow current flow in forward direction. you could do the same by putting lots of single layer diodes in paralleled but in order to split enough voltage off not to burn them all out you would have to use way too many diodes to be economical. this is just a way of making super high voltage diodes with much less silicon.
further more when the current is going forward the thyrister works like a closed switch. but when its going backwards it acts like a big capacitor. the LC inductor is not to help turn off the thyrister so much is its to help ease the massive voltage spikes you would get when the current reverses again and that capaciter turns back onto a switch with extra voltage pushing the capacitor charge out.
the result is that a thyrister rectifier sends ultra high voltage DC pulses down the wire instead of AC or constant DC. the high voltage pulses have the same long distance transmision properties as AC but without the current ever fully reversing, thus causing flux in the wire to reverse, thus cause the wire to expand and contract and generate lots of heat and lose energy.
also the same way that most communication lines work. DC pulses for long distance... with diferential signals to detect voltage errors.
