Do you know that a semiconductor device called a ‘thyristor’ solves the huge issue of power transfer from a generating station to consumers located far away?

Traditional AC power transmissions face huge power losses and also suffer from the issue of stability and controllability. For long distance power transmission, HVDC technology is the right choice. Watch the video from Learn Engineering for more info:
In HVDC, bulk amounts of AC power have to be converted to DC with the help of converting stations. After that the DC power is transmitted to the consumers.
This important task of conversion is performed by a unique semiconductor switching device called a ‘thyristor’, more specifically by silicon-controlled rectifiers. Let’s explore how a thyristor works./Learn Engineering
