A facility that changes electric power into some form that can be stored and usefully reconverted back to electric power, for example, pumped storage or battery systems. power supply A subsystem of a computer or other electronic device that turns electric power from a wall plug or batteries into a form suitable for use by the system.
A steam turbine used to provide electric power. An electric power system is a network of electrical components deployed to supply, transfer, and use electric power. An example of a power system is the electrical grid that provides power to homes and industries within an extended area.
Devices used in electric vehicles consist mostly of dc/dc converters for battery charging and dc/ac converters to power the propulsion motor. Electric trains use power electronic devices to obtain power, as well as for vector control using pulse-width modulation (PWM) rectifiers. The trains obtain their power from power lines.
High voltage direct current systems are one of the elements of an electric power grid. Electric power distribution engineering covers those elements of a power system from a substation to the end customer. Power system protection is the study of the ways an electrical power system can fail, and the methods to detect and mitigate for such failures.
This glossary of power electronics is a list of definitions of terms and concepts related to power electronics in general and power electronic capacitors in particular. For more definitions in electric engineering, see Glossary of electrical and electronics engineering .
Like electrical engineering, EET deals with the "design, application, installation, manufacturing, operation or maintenance of electrical/electronic(s) systems." [ 2 ] However, EET is a specialized discipline that has more focus on application, theory, and applied design, and implementation, while electrical engineering may focus more of a ...
A power module or power electronic module provides the physical containment for several power components, usually power semiconductor devices. These power semiconductors (so-called dies ) are typically soldered or sintered on a power electronic substrate that carries the power semiconductors, provides electrical and thermal contact and ...
Power system protection is a branch of electrical power engineering that deals with the protection of electrical power systems from faults [citation needed] through the disconnection of faulted parts from the rest of the electrical network. The objective of a protection scheme is to keep the power system stable by isolating only the components ...
