HVDC converter station - Wikipedia

An HVDC converter station (or simply converter station) is a specialised type of substation which forms the terminal equipment for a high-voltage direct current (HVDC) transmission line.[1] It converts direct current to alternating current or the reverse. In addition to the converter, the station usually contains: three-phase alternating
