What is an HVDC (High Voltage Direct Current) Transmission

An HVDC converter station uses thyristor valves to perform the conversion from AC to DC and vice versa. The valves are normally arranged as a 12- pulse converter. The valves are connected to the AC system by means of converter transformers. The valves are normally placed in a building and the converter transformers are loed just outside.
