The Silicon-Controlled Rectifier (SCR) - All About Circuits

A silicon-controlled switch (SCS) behaves nearly the same way as an SCR; but there are a few differences: Unlike an SCR, an SCS switches off when a positive voltage/input current is applied to another anode gate lead. Unlike an SCR, an SCS can also be triggered into conduction when a negative voltage/output current is applied to that same lead. SCSs are useful in practically all circuits that need a switch that turns on/off through two distinc… Webb25 nov. 2024 · Following is the list of multiple choice questions in this brand new series: MCQ in Industrial Electronics Principles and Applications.
