Thyristors for HVDC transmission
Physics in Technology, 1988To make HVDC transmission competitive, the number of components - of which thyristors are of paramount importance - must be reduced. This article looks at the fabrication of thyristors with high blocking voltages.

Synchronverter based HVDC transmission
2017 Innovations in Power and Advanced Computing Technologies (i-PACT), 2017This is an innovative control strategy for the High Voltage Direct Current (HVDC) transmission based on synchronverter technology. The control of sending end rectifier mimics a synchronous motor(SM) and the receiving end inverter controls acts as a synchronous generator (SG).

Powerful platform [offshore HVDC transmission]
Power Engineer, 2006Bringing power to one of the world's largest oil and gas platforms was not easy, but Troll A in the North Sea is now reaping the benefits. In February 2005, the world's first offshore HVDC transmission was successfully commissioned. Consisting of two parallel 40 MW transmissions connecting the Troll A gas platform in the North Sea, with the mainland ...
