IT is a rather common occurrence that the resistance of semiconductor rectifiers drifts after application of a voltage. This effect is particularly strong immediately following the application of a ...

Converting ac to dc has been accomplished by several different types of rectifiers through the years. Here are a few of the more common types of rectifiers used in the past 100 years. Mercury arc ...

Used as a semiconductor in rectifiers and suppressors for many years, selenium occurs naturally on the earth. Its popularity as a rectifier is fading in favor of its silicon equivalent. However, ...

CRYSTAL rectifiers, the essential constituents of which are a metal and semiconductor in contact, are of two types, large-area contact rectifiers, such as copper oxide or selenium rectifiers, and ...
