The power range of VSDs start from a few hundred watts and end at tens of megawatts. In industry a common application is the variable speed drive (VSD) that is used to control an induction motor. The power range is typically from tens of watts to several hundred watts. Television sets, personal computers, battery chargers, etc.
An AC/DC converter ( rectifier ) is the most typical power electronics device found in many consumer electronic devices, e.g. In contrast to electronic systems concerned with transmission and processing of signals and data, in power electronics substantial amounts of electrical energy are processed. Middle brook and others beginning in the 1950s. In modern systems the conversion is performed with semiconductor switching devices such as diodes, Thyristor and transistors, pioneered by R. The first high power electronic devices were mercury-arc valves.
It also refers to a subject of research in electronic and electrical engineering which deals with the design, control, computation and integration of nonlinear, time-varying energy-processing electronic systems with fast dynamics. Summary Power electronics is the application of solid-state electronics to the control and conversion of electric power. Power electronics notes by arun kumar pdf.
