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 Electronic, 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. An extensive World Wide Web site http://power.ece.uiuc.edu/krein text includes additional examples, laboratory materials, and author contact.
