CE ÎNSEAMNĂ SILICON-CONTROLLED RECTIFIER ÎN ENGLEZĂ?
Uscător cu comandă cu siliciu
Un redresor controlat cu siliciu este un dispozitiv de control al curentului în patru trepte. Denumirea "redresor comandat cu siliciu" este denumirea comercială a General Electric pentru un tip de tiristor. SCR a fost dezvoltat de o echipă de ingineri de putere condusă de Gordon Hall și comercializată de Frank W. "Bill" Gutzwiller în 1957. Unele surse definesc redresoare și tiristoare controlate cu siliciu ca sinonime, alte surse definesc redresoare comandate cu siliciu ca subset familie de dispozitive cu cel puțin patru straturi de material alternativ de tip N și P, această întreagă familie fiind denumită tiristor. Potrivit lui Bill Gutzwiller, termenii "SCR" și "Controlled Rectifier" au fost mai devreme, iar "Thyristor" a fost aplicat mai târziu, deoarece utilizarea dispozitivului sa răspândit la nivel internațional. SCR-urile sunt dispozitive unidirecționale, spre deosebire de TRIAC-urile care sunt bidirecționale. SCR-urile pot fi declanșate în mod normal numai de curenții care intră în poartă, spre deosebire de TRIAC-urile care pot fi declanșate în mod normal fie de un curent pozitiv, fie de un curent negativ aplicat la electrodul său de poartă.
Definiția silicon-controlled rectifier în dicționarul Engleză
Definiția redresorului controlat cu siliciu în dicționar este un redresor de semiconductor al cărui curent frontal între doi electrozi, anodul și catodul este inițiat prin intermediul unui semnal aplicat unui al treilea electrod, poarta. Curentul devine ulterior independent de semnal. Este un tip de tiristor SCR.
