- Mercury valves
- Thyristor
- Toggle switches
- Mechanical switches
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Line-Commutated Converters (LCC) used in HVDC systems generally use thyristors as the main switching component. Thyristors allow for efficient control of power flow and have been widely used in HVDC systems due to their high reliability and ability to handle high voltage and current levels.
Thus, the correct answer is Thyristor.
