Power distribution | Power Generation and Distribution ... heart of any HVDC system is the converter. As modern power electronics developed, thyristors came to be used for this purpose. In 1975, Siemens initiated the world's first thyristor-operated long-distance HVDC transmission system, between the Cabora Bassa power plant, in what is now Mozambique and the Republic of South Africa.
