Question

Efficient Line-Commutated Converter (LCC) HVDC converters generally use:

• A. Mercury valves
• B. Thyristor
• C. Toggle switches
• D. Mechanical switches

Hint:

Thyristors are commonly used in HVDC converters because of their ability to handle large voltages and currents while offering precise control over power flow.

Answer 1

The Correct Option is B

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.
