Which among the following employs thyristors with no gate turn off capability?

Which among the following employs thyristors with no gate turn off capability? Correct Answer Current-sourced converters

Practically speaking, current-sourced converters employ thyristors with no gate turn-off capability. They are more economical for large HVDC schemes. On the other hand, voltage sourced converters are preferred in FACTS Controllers.
