Book excerpt: The book begins with a two-chapter review of fundamental electricity and magnetism and the algebra needed for understanding transformer theory. The properties of transformers are then introduced and the two basic transformer design equations are discussed thoroughly. The important subject of power losses is discussed next, while a chapter is devoted to both the core and windows. Moving from general design considerations to transformer types, the book covers inductors and power, current and impedance transforms. Also treated are transformers as used in converter, inverter and rectifier circuits finally, practical matters, such as transformer construction with salvaged parts, transformers selected off the shelf and checks and tests which can be made on the completed transformer are dealt with.andWritten in an easy-to-understand manner, this profusely illustrated book will be useful not only to the experimenter who wants to construct a transformer but to anyone wishing to gain a deeper and more concrete understanding of transformers.andContentsandChapter 1: andSymbols, Abbreviations and other ReferenceChapter 2: andElementary ElectromagneticChapter 3: andProperties of TransformersChapter 4: and LossesChapter 5: and The CoreChapter 6: and The WindowsChapter 7: and Summarized Data and General Design ConsiderationsChapter 8: and Power TransformersChapter 9: and Designing for RectifiersandChapter 10: Transformers in Converters and InvertersChapter 11: InductorsChapter 12: The Impedance TransformerandChapter 13: The Current TransformerandChapter 14: Salvage, Construction and SourcesChapter 15: Transformers Off the ShelfChapter 16: Tests and
