The outstanding performance and technologies of State of the Art High Power Thyristors for UHVDC applications are described. HVDC Transmission systems up to 11 GW and voltages of +-1100 kV are planned to be built [1] by using those power semiconductors. Different features (e.g. integrated protection functions) or technologies like low temperature sintering (LTS) for highest surge currents at highest blocking voltages are presented. In addition, a new voltage definition according to application demand is introduced to decrease the number of devices in series connections. Finally, the new 6”- 8.5kV Light Triggered Thyristor (LTT) is introduced.
