Power electronics is the branch of electrical engineering that deals with the processing of high voltages and currents to deliver power that supports a variety of needs.
How Do Power Electronics Work?
Power electronic systems are used in a variety of applications, such as:
Benefits Of Power Electronics
High power density power supplies
Improved efficiency of up to 99% in power conversion
Power can be made available in the desired form and level as per specifications
Increased clean power generation using power electronic interfaces to connect the sources to grid
Wireless power transfer
Application Of Power Electronics
Power electronics is the application of solid-state electronics for the control and conversion of electric power. It provides a basic knowledge of circuitry for the control and conversion of electrical power with high efficiency. The structure of Modern power systems have been separated in three different interlinked sections-generation, transmission and distribution likewise. Mostly the output of generator is always AC, but in some applications we need DC supply, where we get optimum utilization of efficient power with respect to applications example different types of sockets, connectors, switches, and fixtures. High-voltage direct current (HVDC) electric power transmission systems use DC for the bulk transmission of electrical power. Whereas, in some cases we need AC supply and we are supplied with DC quantity there, example transformers, 3Ø motor, etc. In such cases we need to convert AC to DC or DC to AC. This can be done using electronic devices such as SCR, Power BJT, Chopper, etc. In this paper we will study particularly application of SCR, TRIAC, GTO and IGBT in electrical power system.
