Converter substations may be associated with HVDC converter plants, traction current, or interconnected non-synchronous networks. These stations contain power electronic devices to change the frequency of current, or else convert from alternating to direct current or the reverse.

Rectifier - Wikipedia

A rectifier is an electrical device that converts alternating current (AC), which periodically reverses direction, to direct current (DC), which flows in only one direction.. The process is known as rectifiion, since it "straightens" the direction of current.Physically, rectifiers take a nuer of forms, including vacuum tube diodes, mercury-arc valves, stacks of copper and selenium oxide
