A module is a separate unit of software or hardware. Typical characteristics of modular components include portability, which allows them to be used in a variety of systems, and interoperability, which allows them to function with the components of other systems. The term was first used in architecture.
A silicon-controlled rectifier is a semiconductor device that is used as a switch in an electrical circuit.It's a solid state direct current (DC) electronic switch. There is a ton of information including a detailed description of the SCR and a list of applications at the Wikipedia article.A link is posted below. silicon-controlled rectifier is a semiconductor device that is used as a switch in an electrical circuit.
Chapter 3 - Diodes and Rectifiers. Now we come to the most popular application of the diode: rectification. Simply defined, rectification is the conversion of alternating current (AC) to direct current (DC). This involves a device that only allows one-way flow of electrons. As we have seen, this is exactly what a semiconductor diode does. The simplest kind of rectifier circuit is the half-wave rectifier.
