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.
