Description:
High-voltage, direct-current transmission (HVDC) is a method based on modern high-performance electronics for transporting electric power over long distances with low loss. This ends the reliance on alternating current transmission. The advantages of HVDC technology are explained here and their historical development described. In addition basic information is provided about HVDC technology and the electronics elements used, especially thyristors.
