Abstract
There is a growing use of High Voltage Direct Current (HVDC) globally due to the many advantages of Direct Current (DC) transmission systems over Alternating Current (AC) transmission, including enabling transmission over long distances, higher transmission capacity and efficiency. Moreover, HVDC systems can be a great enabler in the transition to a low carbon electrical power system which is an important objective in today’s society. The objectives of the paper are to give a comprehensive overview of HVDC technology, its development, and present status, and to discuss its salient features, limitations and applications.

One of the reasons Alternating Current (AC) systems displaced Direct Current (DC)was because transformers allowed efficient conveyance of electricity by increasing the voltage for transmission and reducing the voltage to a level needed for utilization
The technological development in solid-state devices, converter topologies and control techniques will continue to improve the attractiveness of DC transmission systems
Summary
Was because transformers allowed efficient conveyance of electricity by increasing the voltage for transmission and reducing the voltage to a level needed for utilization. High Voltage Direct Current (HVDC) transmission systems have significant advantages over AC transmission, as will be outlined later. The characteristic AC current harmonics of the 6-pulse bridge of Figure 5 are h = 6n ± 1, n = 1, 2, 3 . The thyristor only turns off when the current drops to zero (actual below its latching current) and this is achieved by firing another thyristor with a higher phase voltage.
