EMC Books

Electromagnetic Compatibility Engineering, by Henry W. Ott, publisher: John Wiley & Sons, hardcover 872 pages, 566 figures, 65 tables. Publication date: August 2009, ISBN#: 978-0-470-18930-6.

Electromagnetic Compatibility Engineering started out being a third edition to my best selling book Noise Reduction Techniques in Electronic Systems, 2nd edition., but it turned out to be much more than that, hence, the title change. Nine of the original twelve chapters were completely rewritten. In addition, there are six new chapters, plus two new appendices, with over 600 pages of new and revised material (including 342 new figures). Most of the new material relates to the practical application of the theory of electromagnetic compatibility (EMC) engineering, and it is based on experience gained from my EMC consulting work, and the teaching of EMC training seminars over the last 20 plus years.

This book is intended primarily for the practicing engineer who is involved in the design of electronic equipment or systems and is faced with EMC and regulatory compliance issues. It addresses the practical aspects of electromagnetic compatibility engineering, covering both emission and immunity. The concepts presented in this book are applicable to analog and digital circuits operating from below audio frequencies up to those operating in the GHz range. Emphasis is on cost-effective EMC designs. Electromagnetic Compatibility Engineering is the most comprehensive book on the subject and reflects all the latest advances and developments in the field.

The book is also written in such a way that it can easily be used as a textbook for teaching a senior level, or continuing education, course in electromagnetic compatibility. To this end, the book contains 251 problems for the student to work out, the answers to which are included in the appendix. The book contains eighteen chapters and six appendices, almost 900 pages.

Electromagnetic Compatibility Engineering stands out from other EMC books in a number of ways:

1. The comprehensiveness of the coverage. While still containing all the normal EMC subjects such as cabling, shielding, grounding, digital circuit layout, and ESD, Electromagnetic Compatibility Engineering includes coverage of:

    •    Equipment/Systems Grounding
    •    Balancing and Filtering
    •    Passive Components
    •    Radiated Emissions
    •    Conducted Emission
    •    Switched-Mode Power Supplies
    •    Variable-Speed Motor Drives
    •    Harmonic Emission
    •    Digital Circuit Decoupling
    •    PCB Layout and Stackup
    •    Mixed Signal PCB Layout
    •    RF and Transient Immunity
    •    Power Line Disturbances
    •    Pre-Compliance EMC Measurements
    •    EMC Regulations
    •    Contact Protection
    •    Intrinsic and Active Device Noise Sources
    •    The Theory of Partial Inductance

2. The critical balance between theory and practical applications. Most EMC books either overemphasize the theoretical aspects of EMC, swamping the reader with mathematics and the derivation of equations, or give “cook book” solutions to EMC problems with little or no theory to back them up. Electromagnetic Compatibility Engineering strikes a critical balance by providing sufficient theory for the reader to be able to understand the principle being discussed, but no more than necessary. In this way the reader understands “why” the principle is applicable, and is therefore capable of applying the theory to other situations.

3. The clarity of the writing. Complex issues are broken down into their fundamental parts and explained in a very straightforward easily understood manner. The primary objective of the book has been to explain the subject in a manner easily understood by the typical product design engineer. In other words, I wrote the book so I could understand it.

4. Considerable new and unique material. For example, the measurements of ground plane inductance, the exact ground plane current distribution for microstrip, stripline and asymmetrical stripline transmission lines, how digital logic currents actually flow in a PCB, the use of embedded PCB capacitance for decoupling, mixed-signal PCB layout, and the appendix on the theory of partial inductance. Much of this material is not available elsewhere.
