For a HVDC transmission scheme, the DC smoothing reactor provides a number of functions but principally it is used to: 1. Reduce the DC current ripple on the overhead transmission line or cable, 2. Reduce the maximum potential fault current that could flow from the DCSee more on electrical-engineering-portal TI [PDF]

In order to convert high voltage AC power to DC power, two technologies are available, classical Line Commutated Converter (LCC) and the Voltage Source Converter (VSC).
