Old radios often had selenium rectifiers to convert AC to DC. The problem is that the old units, dating back to 1933, are prone to failure and to release dangerous chemicals like hydrogen selenide. [M ...
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. Rajendranath K ...
EL SEGUNDO, Calif.--(BUSINESS WIRE)--International Rectifier, IR® (NYSE: IRF), a world leader in power management technology, announced today with deep regret that Eric Lidow passed away on January 18 ...
At the time Selenium Corp. produced the new rectifiers, Lidow did not know how they ultimately would be used. Years later, he learned that the rectifiers served as proximity fuses in munitions, ...
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 ...
It is shown how the image force can be taken into account very simply by making a minor improvement in the current theory of rectification. The equations obtained have been compared with experimental ...
