All Rights Reserved世允电源网,论坛电工程师BBs.21dianyuan.com设计灵感之源ForewordColonel McLyinan is a well-known author, lecturer, and magnetic circuit designer. His previous books ontransformer and inductor design, magnetic core characteristics, and design methods for converter circuitshave been widely used by magnetics circuit designerIn this book, Colonel Mclyman has combined and updated the information found in his previous bookHe has also added several new subjects such as rotary transformer design, planar transformer design, andplanar construction. The author covers magnetic design theory with all of the relevant formulas along withcomplete information on magnetic materials and core characteristics. In addition, he provides real-world,step-by-step design examplesThis book is a must for engineers working in magnetic design. Whether you are working on high"?state-of-the-art design or high-volume or low-cost production, this book is essential.

All Rights Reserved世允电源网,论坛电工程师BBs.21anyuan.com设计灵感之源PrefaceI have had many requests to update Transformer and Inductor Design Handbook, because of the waypower electronics has changed over the past few years. This new edition includes 21 chapters, with newTopics such as: The forward converter, flyback converter, quiet converter, rotary transformers, and planartransformers, with even more design examples than the previous editionThis book offers a practical approach, with design examples for design engineers and system engineers inthe electronics and aerospace industries. Transformers are found in virtually all electronic circuits. Thisbook can easily be used to design lightweight, high-frequency aerospace transformers or low-frequencycommercial transformers. It is, therefore a design manualThe conversion process in power electronics requires the use of transformers, components that frequentlyare the heaviest and bulkiest item in the conversion circuit. trans. former components also have a significanteffect on the overall performance and efficiency of the system. Accordingly, the design of suchtransformers has an important influence on overall system weight, power conversion efficiency, and costBecause of the interdependence and interaction of these parameters, judicious trade-offs are necessary toachieve dcsign optimizationManufacturers have, for years, assigned numeric codes to their cores to indicate their power-handlingbiThis method assigns to each core a number called the area product, an, that is the product of itswindow area, Wa, and core cross-section area, Ac. These numbers are used by core suppliers to summarizedimensional and electrical properties in their catalogs. The product of the window area, Wa, and the coretrea, Ac, gives the area Product, Ap, a dinension to the fourth power. I have developed a new equation fothe power-handling ability of the core, the core geometry, Kg. Kg has a dimension to the fifth power. Thisnew equation provides engineers with faster and tighter control of their design. It is a relatively newconcept, and magnetic core manufacturers are now beginning to include it in their catalogsBccausc of thcir significance, the area product, Ap, and the core geometry, Kg, are treated extensively in thishandbook. A great deal of other information is also presented for the convenience of the designer Much ofthe material is in tabular form to assist the designer in making the trade-offs best suited for a particularapplication in a minimum amount of timeDesigners have uscd various approaches in arriving at suitable transformer and inductor designs. Forexample, in many cases a rule of thumb used for dealing with current density is that a good working level is1000 circular mils per ampere. This is satisfactory in many instances; however, the wire size used to meetthis requirement may produce a heavier and bulkier inductor than desired or required.
