EMI Filter Design Second Edition Revised and Expanded by Richard Lee Ozenbaugh pdf free download. Over the last twelve years, I have made friends with many EMI “gurus” across the United States, but primarily in the Southwest. Many have attended my EMI Design seminars and I have met others as an Applications engineer in the field. My desire was to increase my knowledge of EMI filter design by learning new and better techniques.

I concluded, after some years, that very few of them had a concrete method for the design of these low pass filters (it is black magic, isn’t it?). I got to know most of these engineers quite well. They would give me a very strange look when I would ask them this leading question: “What is your design technique?” I finally concluded that in most cases it depended on what was handy or readily available. They would have a certain capacitor or inductor on their bench or in stock (or readily available from a supplier).

At best, they would calculate the needed inductor(s), or capacitor(s), to arrive at the desired loss. Some would give me profound statements such as, “We design for maximum loss!” or “We use [a certain program] to get the values needed.” To accomplish this latter method, the “guru” would reach the desired loss by backward-engineering the network—modifying the inductor or capacitor values or changing the number of components to get the apparent desired loss. Some designs had so much capacitance across the line that the EMI filter inrush current, added to the power supply filter capacitors charging currents, would trip the circuit breaker.
