"THYRISTORS" are certainly handy devices, but tere is not any comparison to the effect of transistors even in power electronics. This video is part of why I call it the cartoon channel.

 

MB; I have to -somewhat- disagree with your assessment.
It is absolutely true that thyristors did not have the breadth of impact on electronics as the transistors did. But when it comes to power electronics, it was an absolute game changer.
In modern times both MOSFETs and IGBTs are now challenging SCRs, but for about 40 years since their introduction, they dominated power electronics.
I also agree that for the most part YT has become a cartoon channel, but there are a few channels, Asianometry being one of them, that I find valuable.

Absolute NO on both points. Did you even watch the video?

Thyristors are what made multi 10's of KW of ADJUSTABLE power ( SCR phase controlled regulated power supplies) in a human lift-able power supply possible. The universe of manufacturing machines was created because of them.


SCR controlled power supplies like this are what made modern transistors and chips possible

Did you know that a semiconductor device called a thyristor plays a crucial role in solving the challenge of transferring power over long distances from generating stations to distant consumers? Traditional AC power transmission often suffers from significant energy losses and faces issues with stability and control. For long-distance power transmission, High Voltage Direct Current (HVDC) technology is the preferred solution.

In HVDC systems, large amounts of AC power need to be converted to DC using conversion stations. Once converted, the DC power is then transmitted to consumers. This conversion task is handled by a special semiconductor switching device known as a thyristor, specifically silicon-controlled rectifiers (SCRs).
