An electrical machine translates its input electrical power into an output mechanical power i.e. it is an electromagnetic energy conversion device. Electrical machines have been available and working for nearly a century. During this period many extensive efforts have been made by researchers worldwide to develop and improve design, configuration, and performance of electrical machines. They may be categorized according… Read More »
The sinusoidal pulse width modulation (SPWM) is one of the most popular modulation technique used in wide range of industrial application where power switching converter are employed. Low ratio of carrier frequency (fc) to modulation frequency (fm) is the best from of modulation for high power application.
Power Line Communication (PLC) refers to provisioning of communication services over the electricity power grid. The main characteristics of PLC involves sending high frequencies using a PLC Carrier unit over power lines and injecting the frequencies (or picking them up) via a coupler linked directly to the power grid.
