Silicon Controlled Rectifier - Wikipedia
A silicon controlled rectifier or semiconductor controlled rectifier is a four-layer solid-state current-controlling device. The principle of four-layer p–n–p–n switching was developed by Moll, Tanenbaum, Goldey and Holonyak of Bell Laboratories in 1956. ... Access Doc

Thyristor, Silicon Controlled Rectifiers, SCR Module | C&H ...
Thyristor products are also called a SCR (Silicon Controlled Rectifiers). A SCR Module is used to control and rectify current in only one direction. The SCR module works like a mechanical switch: it is either on or off. When a current/voltage pulse is applied to the gate of the SCR, it triggers on and starts to conduct. ... Doc Viewer

Thyristor Or Silicon Controlled Rectifier Tutorial
It is a multi-layer semiconductor device, hence the “silicon” part of its name. It requires a gate signal to turn it “ON”, the “controlled” part of the name and once “ON” it behaves like a rectifying diode, the “rectifier” part of the name. ... Retrieve Doc

UNDERSTANDING SCR POWER CONTROLS
A silicon controlled rectifier (SCR) is a solid state switching device which can provide fast, infinitely variable proportional control of electric power. Not only does this give maximum control of your heat process, but it can extend heater life many times over other control methods. Since the SCR is solid state, it ... Doc Viewer

The Silicon-Controlled Switch (SCS) | Thyristors ...
A silicon-controlled switch, or SCS, is essentially an SCR with an extra gate terminal. Typically, the load current through an SCS is carried by the anode gate and cathode terminals, with the cathode gate and anode terminals sufficing as control leads. An SCS is turned on by applying a positive voltage between the cathode gate and cathode ... Visit Document

SCRs: What Are They And How Do They Work?
The output current controlled is huge by comparison (just like a relay), but there is no arcing and no contacts to pit. Like all diodes, SCR’s can allow current to flow in one direction only; therefore, they are used in pairs for the conduction of AC current. Earl Dean.
