Major components of the HVDC converter station (single ...· 4. Converter Transformer. The converter transformer is the interface between the AC system and the thyristor valves. Typically the HVDC converter transformer is subjected to a DC voltage insulation stress as well as the AC voltage stress normally experienced by a power transformer. These AC and DC stresses are fundamentally different.
HVDC converter - Wikipedia HVDC converter converts electric power from high voltage alternating current (AC) to high-voltage direct current (HVDC), or vice versa. HVDC is used as an alternative to AC for transmitting electrical energy over long distances or between AC power systems of different frequencies. HVDC converters capable of converting up to two gigawatts (GW) and with voltage ratings of up to 900 kilovolts ...
