solid-state relay A solid-state relay is less-commonly referred to by its acronym, SSR. It is sometimes regarded as an optocoupler, but in this encyclopedia the two components have separate entries. An optocoupler is a relatively simple device consisting of a light source (usually an LED) and a light sensor, in one package. It is used […]

triac:What It Does,Symbol Variants,How It Works,Quadrants,Threshold, Latching, and Holding Current,Triac Testing,Breakover Voltage,Switching AC,Triac Triggered by a Diac and Other Triac Drivers.
triac A triac is a gate-triggered type of thyristor. Its name was probably derived from the phrase “triode for AC,” and because it is not an acronym, it is not usually capitalized. A thyristor is defined here as a semiconductor having four or more layers of p-type and n-type silicon. Because the thyristor predated integrated […]

SCR:What It Does,How It Works,Switching Behavior,Internal Configuration,Breakdown and Breakover Voltage,SCR Concept Demoand AC Current Applications.
SCR The acronym SCR is derived from silicon-controlled rectifier, which is a gate-triggered type of thyristor. A thyristor is defined here as a semiconductor having four or more alternating layers of p-type and n-type silicon. Because it predated integrated circuits, and in its basic form consists of a single multilayer semiconductor, a thyristor is considered […]

diac A diac is a self-triggering type of thyristor. Its name is said to be derived from the phrase “diode for AC,” and because it is not an acronym, it is not usually capitalized. A thyristor is defined here as a semiconductor having four or more layers of p-type and n-type silicon. Because the thyristor […]

Simplified magnetic amplifier circuitry , summary of special amplifiers and answers to questions q1. Through q50.
SIMPLIFIED MAGNETIC AMPLIFIER CIRCUITRY If the saturable-core reactor works, why do we need to add a rectifier to produce a magnetic amplifier? To answer this question, recall that in NEETS, module 2 – Introduction to Alternating Current and Transformers, you were told about hysteresis loss. Hysteresis loss occurs because the a.c. applied to a coil […]
