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.
6.1 Rectifier. A rectifier is an electrical device that converts alternating current (AC) to direct current (DC), a process known as rectification. Rectifiers have many uses including as components of power supplies and as amplitude modulation detectors (envelope detectors) of radio signals.ectification is the conversion of alternating current (AC) to direct current (DC). A half-wave rectifier is a circuit that allows only one half-cycle of the AC voltage waveform to be applied to the load, resulting in one non-alternating polarity across it.
