HVDC Transformers ~ Electrical Knowho converter transformer is generally built with two valve windings (see fig.3) of equal power and voltage ratings. One of the windings is connected in star and the other in delta. With this arrangement the dominant harmonics from the converter will be cancelled …
HVDC converter stations - Hitachi ABB Power Grids is converted from alternating current (AC) to direct current (DC) and vice versa in a converter station. This is done by means of high-power, high-voltage electronic semiconductor valves. A semiconductor valve is a device that can carry current in one direction only, and which prevents current from flowing in the opposite direction.
