HVDC Converters Market Outlook 2025 | Industry Share Report Converters Industry Background. An HVDC converter is an electronic device that converts High Voltage Alternating Current (HVAC) to High Voltage Direct Current (HVDC) and vice versa. A complete HVDC system includes minimum one converter operating as a rectifier (converts AC to DC) and one operating as an inverter (converts DC to AC).
HVDC Transformers | Transformers | Siemens Energy Global transformers are used as coupling elements between AC grids and high-power rectifiers for very long overhead lines or submarine cables. Converting AC lines to DC can help increase the power transfer volume through existing rights of way and typically cuts line losses by 30-50%.
