===Power conversion=== {{Main article|Rectifier}} [[File:ACtoDCpowersupply.png|250px|thumb|Schematic of basic AC-to-DC power supply]] [[Rectifier]]s are constructed from diodes, where they are used to convert [[alternating current]] (AC) electricity into [[direct current]] (DC). Automotive [[alternator (auto)|alternators]] are a common example, where the diode, which rectifies the AC into DC, provides better performance than the [[Commutator (electric)|commutator]] or earlier, [[electrical generator|dynamo]]. Similarly, diodes are also used in ''[[Cockcroft-Walton generator|Cockcroft–Walton]] [[voltage multiplier]]s'' to convert AC into higher DC voltages.
