EMI Filter Design

I rented this book for a month to see if it would help with solving some filtering issues I was having related to a MIL-STD-461 design. I had to read it at least 3 times to understand what it was talking about, but in the end I was MUCH more confident in my ability to design filters. When it was all over I decided to buy the book to add to my library (my memory isn't what it used to be).

The book was good. The delivery was later.

Let me start by saying I know Richard Lee Ozenbaugh "Oz". He was a consultant on a project I worked on back in 2003-2004. His knowledge of filter design and of real-world components proved to be invaluable in getting my staff up to speed and delivering a product that worked in a short amount of time. This book, now in its third edition contains a wealth of experience and knowledge Oz gained over his career. While there isn't anything hard about designing EMI filters, there are many places where the real world causes problems that you didn't plan on when you designed the schematic. Oz covers these issues: parasitics, capacitor lead lengths, magnetic coupling, core saturation, component arrangement/placement, etc. He also provides some great chapters on choosing component values toward the end of the book that will get you up and going in whatever computer simulation you prefer in no time. Do I like the book? Yes. It's the kind of book that you keep handy for when you need to tackle a tough filter problem and you don't have time to make dumb mistakes in design that cost you valuable project time.

J'avais acheté la seconde édition il y a quelques années. Le contenu était intéressant mais la procédure à suivre pour le design d'un filtre était un peu confuse. J'ai hésité avant de réinvestir dans cette troisième édition en me demandant si le contenu additionnel en valait la peine. Cette troisième édition est une belle réorganisation et je ne regrette pas de l'avoir acquise. Les explications sont plus claires, la lecture est assez rapide.Je conseille vivement d'acheter ce livre à toute personne qui doit dimensionner des filtres CEM. Il existe très peu de livres qui donnent les critères à adopter lors du design de tels filtres.
