Significant advances in high-voltage direct current (HVDC) transmission are in step with rapid changes to energy systems worldwide. Shortly after POWER magazine began publication in 1882, the ...

Modular multilevel converters (MMCs) have emerged as the preferred topology for voltage-source high-voltage direct current (HVDC) transmission, owing to their scalability, superior waveform quality ...

To date, all Voltage Source Converters (VSC) used in HVDC networks are incapable of clearing faults on the DC side of the converter. “For most of the situations where such converters have been used so ...

We have been looking at the history of some HVDC devices such as the mercury-arc valve and the thyristor valve for the past few months. The mercury-arc valve made HVDC transmission possible (1950s), ...
