Description:

The concept and calculation of "partial inductances" are essential to the prediction of power rail collapse and ground bounce problems. Yet, this concept is not currently taught in undergraduate Electrical Engineering programs and is not understood by the majority of engineering professionals. This is the first book devoted solely to the subject of inductance; it is found piecemeal and in very limited discussion in books on general electromagnetic fields.Formulae for the loop and partial inductances of virtually all situations of practical interest are derived in this book. The derivation is supplied, not just the formula, so that readers can determine the limits of the formula's use--…
