The titles of these 3 4 parts give the general feel for the detailed content. The emergence of binary decision diagrams (BDDs) as a powerful new tool in logic design is given good emphasis, but test remains a very poor relation in this recent research. E,ach chapter, however, is authoritative in its coverage, but the number of references given at the end of many chapters is disappointing. Inevitably many chapters cover the author’s own research work, which may perhaps be very specific. Nevertheless this is a very useful text for bringing together new ideas, and should be a useful reference text for research students and others engaged in this field. XL.

Robbins (2nd editiorz), John Wiley, Chichester, 1995, 802pp., ISBN: o-471-30576-6, A22.50 Many old, familiar, power electronics books were revised in the early nineties to catch up with the

remarkable ascent of IGBT device technology and the continuing evolution of other power-semiconductor devices, the significant increase in the switching frequency employed in switched-mode power conversion, the design implications oflinefrequency harmonic and EM1 emission regulations about to take full effect in Europe, and the characteristics and design of new classes of circuits which become viable given one or more of these developments, e.g. resonant-mode power converters, active power-factor correction preregulators for off-line power converters, and high response AC machine drives. However, these oldies rarely match a new breed of book which addresses the fundamentals of conventional and new power electronics in a more generalised, well illustrated, highly readable, but no less thorough, way. Power Electronics Converters, Applications and Design is a good example of this new breed. Its chapters are divided into seven groupings and provide broad and competent coverage of the f&dame& operating principles, characteristics and applications of line-frequency converters, high-frequency switching converters, motor drives and power semiconductor devices. The practical design section is confined to snubbers, device drive circuits, heatsinks and magnetic component design. After five years it has undergone its first revision. The expanded second edition includes: two new chapters of introductory material on basic electrical and magnetic circuit concepts and computer simulation issues; expanded, more comprehensive, heatsink and magnetic component design material; improved line-frequency converter treatment; and some revision of semiconductor device material. The revisions are well incorporated and likely to prolong the book’s relevance to students and engineers at all stages of power electronics study and work. The new chapter on power electronics simulation issues, and the supporting MATLAB and PSPICE worked examples and problems, are particularly welcome since simulation tools are

increasingly being used for gaining rapid insight into system operation, or for verifying the functionality and optimising the performance of new designs. Although, perhaps, simulator flexibility could have been emphasised a little more by involving it in heatsink design validation, using existing non-linear magnetic-core models to validate magnetic-component design examples, and including mechanical aspects in some drives examples. Revision within the power-semiconductor devices and drives chapters has been largely confined to: consolidating previously interspersed snubber-circuit material in a separate snubber chapter; adding details on the switching characteristics of emerging MOS-controlled thyristors; expanding discussion on power-integrated-circuit (PIC) geometries and their potential; and expanding details and comparing alternative semiconductor materials for power devices, such as, GaAs, SIC and diamond. This final 3 i page addition is a little perplexing since such knowledge is unlikely to be usable for a very long time. Prospective and practising engineers with power electronics involvement might

have been better served by including more discussion on, for example, the capacity, charge and discharge characteristics, and the powerelectronics requirements of alternative battery technologies and growing portable equipment applications; the background behind a growing commercial interest in hybrid and fully electric vehicle drives and the current state-of-the-art; automotive power electronics generally; and other existing and potentially high-volume power electronics applications. It does seem a pity that it may be possible to read the full contents of this book and appreciate the advantages of imaginary diamond power devices better than what constitutes a light-dimmer switch, or the nature and operation of power electronics circuits and systems used in washing machines, microwave ovens, televisions, video recorders, PCs and their peripherals, photocopiers, cameras or under the bonnet of a car. Perhaps a future challenge for the authors of this superb book would be to weave more examples of relatively mundane, but very widely used, power electronics into the exercises and the text. F. V. P.
