COURSE DESCRIPTION:

Power conditioning is the enabling technology necessary for interfacing various distributed generator (DG) systems to electric utility and to power stand-alone loads. Power semiconductor devices are examined from an application perspective. After examining the basic conversion blocks, the course delves into suitable power conversion architectures (topologies). Examples include: (a) Fuel Cell power conversion system with battery/super-capacitor type energy storage for powering stand-alone residential loads with an option to interface to electric utility; (b) Power conversion architectures for a high speed gas turbine (microturbine) type DG; (c) Suitable converters for fuel cell turbine hybrid will also be considered.

Power electronics is an enabling technology for almost all electrical applications. The field is growing rapidly because electrical devices need electronic circuits to process their energy. Elements of Power Electronics, the first book to discuss this subject in a conceptual framework, provides comprehensive coverage of power electronics at a level suitable for novices in the field. It aims to establish a fundamental engineering basis for power electronics analysis, design, and implementation. More than 160 examples and 350 chapter problems support the presented concepts.
