It is required to implement the HVDC system using the thyristors in large numbers. Why it becomes necessary to use a large number of thyristor switches? Correct Answer Due to low voltage rating of thyristor switches

Thyristors have low voltage rating and to achieve high voltage, a series of switches that have to used.
