High Voltage Direct Current Transmission (HVDC)
Revista de Operaciones Tecnologicas, 2023 High Voltage Direct Current (HVDC) transmission links are currently in operation throughout the world. Until a few years ago, what has limited the use of this way of transmitting power has generally been its cost, but with the advances in power electronics in reducing costs in thyristors: higher rated voltage and current, and simplification of the ...
