“…This combination is made in a very fast way using the fast Fourier transform. The partial inductance approach has been used in the partial element equivalent circuit (PEEC) method [ 62 ] for the electromagnetic modeling of power electronic modules [ 63 ], antennas [ 64 ], high voltage transmission lines [ 65 ] or printed circuit boards (PCBs) [ 66 ], but it is the first time, to the authors’ best knowledge, that it is proposed for obtaining the phase inductances of IMs. Compared with the WFA, this novel method is characterized by the following main points: The conductor, instead of the coil, is used as the basic winding unit, which simplifies the modeling of arbitrarily complex winding layouts.…”

The development of advanced fault diagnostic systems for induction machines through the stator current requires accurate and fast models that can simulate the machine under faulty conditions, both in steady-state and in transient regime. These models are far more complex than the models used for healthy machines, because one of the effect of the faults is to change the winding configurations (broken bar faults, rotor asymmetries, and inter-turn short circuits) or the magnetic circuit (eccentricity and bearing faults). This produces a change of the self and mutual phase inductances, which induces in the stator currents the characteristic fault harmonics used to detect and to quantify the fault. The development of a machine model that can reflect these changes is a challenging task, which is addressed in this work with a novel approach, based on the concept of partial inductances. Instead of developing the machine model based on the phases’ coils, it is developed using the partial inductance of a single conductor, obtained through the magnetic vector potential, and combining the partial inductances of all the conductors with a fast Fourier transform for obtaining the phases’ inductances. The proposed method is validated using a commercial induction motor with forced broken bars.

“…Since then, it has been developed through a series of remarkable developments over the years, which have made it more robust and reliable [8]. Indeed, it has been used to model EM problems in various fields including power plane-pair [9], [10], decoupling capacitors [11], [12], PCB prelayout power integrity analysis [13], power modules [14], [15], on-chip interconnections [16], shielding [17], and antennas [18], [19].…”

Fast Fourier transform (FFT)-accelerated integralequation-based electromagnetic (EM) simulators have gained attraction for their capability to compute parasitics of arbitrarily shaped and large-scale voxelized structures on a desktop computer. Yet, FFT-based solvers have limitations due to the necessity of using voxels of the same size in all three Cartesian dimensions and suffer in the case of geometries with far-apart objects that require meshing also the air between them, resulting in a huge number of voxels and, thus, of unknowns. This work aims to overcome both these limitations by developing a systematic anisotropic strategy to compute matrix-vector products using the FFT-based approach and to remove the air existing between objects without sacrificing the desirable features of the FFT-based approach. The proposed approach is presented in the framework of the partial element equivalent circuit (PEEC) method, but it is well suited to be used also with other integral equationbased methods. The accuracy, efficiency, and applicability of the proposed anisotropic and optimized FFT (aoFFT)-based PEEC solver are demonstrated in the example of two structures requiring to use voxels of different sizes along the three Cartesian dimensions and with a large portion of air between the objects.

In this paper, a stochastic analysis method is proposed for extraction and evaluation of power distribution map (PDM) in system printed circuit board (PCB). This is conducted based on some high level data including placement and routing geometry, power distribution network (PDN), component package parasitic, and voltage regulator module (VRM). A simple model for supply current of two constituent blocks of electronic systems is analytically extracted. The worst-case simultaneous operation of all consumers are considered for PDM extraction. The approach is applied to a specific designed and fabricated mixed signal board. PDM is beneficial in the placement process of decoupling capacitance or noisy components in an optimum and right location. Also, the proposed approach can be considered as a verification step of PCB design flow and be applicable before routing only based on the placement data of components of the system. This enables the designer to predict the upcoming problems in layout and hastens the process of design verification.
