What is an HVDC (High Voltage Direct Current) Transmission ... HVDC converter transformer can be built as three-phase units or as single-phase units depending on voltage and power rating. When built as three-phase transformers there is generally one unit with the valve winding arranged for star connection and the other unit for delta connection. In single-phase design, the two valve windings are generally built on the same transformer unit.
