Solid-state HV dc transmission technology

Studies have been made during the past few years to determine the feasibility of employing thyristors in high-voltage dc converter terminals. Overall objectives have also included the integration of solid-state circuitry in order to take advantage of the fast response times associated with thyristors. Because of their advantages over mercury valves, from the point of view of economy as well as performance, a bright future is seen for these solid-state devices in the dc power field.
