Inductance Computations

This chapter presents an approach where we solve inductance problems for a multitude of configurations and applications. It starts with the basic concept of the computation of loop inductances for N loops and shows an example of such a loop structure for which the inductance needs to be computed. Inductance estimations can be performed for simple geometries using approximate models. All the modified nodal analysis (MNA) circuit solver techniques can be applied for a problem with arbitrary conductor arrangements. Any problem can be solved using these circuit solution techniques. The flux that contributes to the inductance is confined inside the loop and need to show how the flux is also confined using partial inductances. In many practical problems, the flux associated with a PEEC circuit with multiple branches can be quite complicated and it may not be obvious why the circuit laws apply for the general case, however, PEEC models satisfy Maxwell's equations.
