The application of power electronics to facilitate the transmission or conversion of electric power has been well known. This document presents a different class of electronic power applications: power electronic circuits are deployed to create small but perceptible signals online. The signals are used for monitoring, power line communication and other information-oriented purposes. We use the term "electronic power signaling technology (PE)" to designate the technologies involved in these applications.
Power Electronics is the application of solid state electronics for the control and conversion of electric power. The first high-powered electronic devices were mercury arc valves. In modern systems the conversion is done with semiconductor switching devices such as diodes, thyristors and transistors, initiated by R. D. Middle-brook and others since the 1950s. Unlike electronic systems related to the transmission and processing of signals and data, substantial amounts of electrical energy are processed in power electronics. An AC / DC converter (rectifier) is the most typical electronic power device found in many consumer electronics, Televisions, personal computers, battery chargers, etc. The power range is typically from tens of watts to several hundred watts. In industry a common application is the speed variator (VSD) that is used to control an induction motor. The power range of the VSDs starts from a few hundred watts and ends up in tens of megawatts.
