The process is known as rectification. Physically, rectifiers take a number of forms, including vacuum tube diodes, mercury-arc valves9 solidstate diodes, silicon-controlled rectifiers and other silicon -based semiconductor switches, Rectifiers have many uses, but are oftenfoundservingascomponentsofDCpower supplies and high-voltage direct current power transmission systems.
