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 ...
The Braun TS2 radio was a state-of-the art tube set in 1956. Today it still looks great, but unsurprisingly, the one that [Manuel Caldeier] has needed a little tender loving care. The table radio had ...
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 ...
Bending a selenium rectifier disk causes a temporary increase of the current flowing through it in both directions. The effect (discovered in December 1942) is especially pronounced in the reverse ...
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 ...
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 ...
