HVDC Technology Line Commutated Converters· PDF fileTransformer Converter Interface HVDC • Match valve voltage with system AC-side • Provide impedance to limit the short circuit current to the valve • Galvanically separate the AC- and DC-side (takes place inside transformer, between AC and DC winding) making it possible to connect the converters in series
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%.
