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 undergraduate book to discuss this subject in a conceptualframework, provides comprehensive coverage of power electronics at a level suitable for undergraduate student engineers, students in advanced degree programs, and novices in the field. It aims to establish a fundamental engineering basis for power electronics analysis, design, and implementation,offering broad and in-depth coverage of basic material. The text's unifying framework includes the physical implications of circuit laws, switching circuit analysis, and the basis for converter operation and control. Dc-dc, ac-dc, dc-ac, and ac-ac conversion tasks are examined and principles ofresonant converters and discontinuous converters are discussed. Models for real devices and components are developed in depth, including models for real capacitors, inductors, wire connections, and power semiconductors. Magnetic device design is introduced, and thermal management and drivers forpower semiconductors are addressed. Control system aspects of converters are discussed, and both small-signal and geometric controls are explored. Many examples show ways to use modern computer tools such as Mathcad, Matlab, and Mathematica to aid in the analysis and design of conversion circuits.Featuring a fundamental approach to power electronics coupled with extensive discussion of design and implementation issues, Elements of Power Electronics serves as an ideal text for courses in power electronics and as a helpful guide for engineers new to the field. Special features of the textinclude: DT More than 160 examples, particularly design examples, and 350 chapter problems that support the presented concepts.
