Abstract

A method is given to reduce very large networks, consisting of self-inductors and mutual inductors only, to much smaller, but mathematically exact, equivalent circuits. The main application is in electrical packaging analysis where multilevel wiring interconnections are modeled as purely inductive networks. These networks are generally too large to fit in available circuit analysis programs. The equivalent circuits fit easily. In typical applications, networks having 300 to 600 self inductors and 15000 to 100000 mutual inductors are reduced to equivalent circuits having 2 to 8 self-inductors and 1 to 36 mutual inductors.
