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.

What is HVDC (High Voltage Direct Current Transmission ... HVDC substation or converter substation rectifiers and inverters are placed at both the ends of a line. The rectifier terminal changes the AC to DC, while the inverter terminal converts DC to AC. The DC is flowing with the overhead lines and at the user end again DC is converted into AC by using inverters, which are placed in converter ...
Power inverter - Wikipedia power inverter, or inverter, is a power electronic device or circuitry that changes direct current (DC) to alternating current (AC). The resulting AC frequency obtained depends on the particular device employed. Inverters do the opposite of "converters" which were originally large electromechanical devices converting AC to DC.
How ready is the switchgear industry to abandon SF₆, the ...· However, due to its excellent technical properties, SF 6 has been increasingly used as an insulating and switching medium in HV and MV sectors since the 1950s.One of its main advantages is that it allows for more compact installations, in particular compared to air-insulated switchgear.This is an especially important criterion in urban areas where space is limited.
