Predicting magnetic coupling of power inductors

This paper proposes a new method to indirectly consider the magnetic material of rod core coils for Partial Element Equivalent Circuit (PEEC) simulations by adapting the number of turns. This way of modeling can be extended to the coupling effects in Common Mode (CM) chokes caused by Differential Mode (DM) currents passing through them. Thereby, sufficiently accurate instant magnetic coupling modeling of current paths which have inductive components is possible.
