More than one century ago, in 1902, American engineer Peter Cooper Hewitt (1861–1921) derived the mercury arc-rectifier, enclosed in a glass bulb, from his mercury-vapor lamp of the previous year. He devised its use for feeding dc motors from alternating currents. As the first rectifier for power uses (two years before Fleming’s diode and four before De Forest’s audion [1]), the mercury arc-rectifier marked the birth of power electronics.

Abstract
More than one century ago, in 1902, American engineer Peter Cooper Hewitt (1861–1921) derived the mercury arc-rectifier, enclosed in a glass bulb, from his mercury-vapor lamp of the previous year. He devised its use for feeding dc motors from alternating currents. As the first rectifier for power uses (two years before Fleming’s diode and four before De Forest’s audion [1]), the mercury arc-rectifier marked the birth of power electronics.File in questo prodotto:
