Application of Extrapolation Capability of Vector Fitting for Out-of-Band Dominant Modal Synthesis of Voltage-Source Converters

open access: yesIEEE Open Access Journal of Power and Energy
Conventional state-space-based stability assessment method of voltage-source converters (VSCs) can be hindered by the black-box feature. Black box-based state-space model identification method using the terminal admittance/impedance frequency responses ...

Package Macromodeling via Time-Domain Vector Fitting [PDF]

open access: yes, 2003
—This paper addresses the construction of lumped macromodels for package structures. A technique named Time-Domain Vector Fitting (TD-VF) is introduced for the identification of the dominant poles of the structure.

Vector Fitting of Noisy Frequency Responses via Smoothing Regularization [PDF]

open access: yes, 2022
We present a simple and effective strategy to compute reduced-order rational macromodels from noisy frequency responses. The reference macromodeling engine is the basic Vector Fitting (VF) scheme, which is well known to be sensitive to noise in the ...

Vector fitting realisation of exact time domain modal nonreflecting boundary condition [PDF]

open access: yes, 2010
To employ the modal nonreflecting boundary condition (MNRBC) in cylindrical coordinates in the finite element time domain (FETD) method, a time domain kernel expression must be found that it is the inverse Laplace transform (ILT) of a known frequency ...

Faster 3D finite element time domain : Floquet absorbing boundary condition modelling using recursive convolution and vector fitting [PDF]

open access: yes, 2009
A recursive convolution (RC) based on the vector fitting (VF) method and triangular temporal basis functions is employed to compute the Floquet absorbing boundary condition (FABC) formulation in the vector 3D finite element time-domain (FETD) modelling ...

Improving the Convergence of Vector Fitting for Equivalent Circuit Extraction From Noisy Frequency Responses [PDF]

open access: yes, 2006
The vector fitting (VF) algorithm has become a common tool in electromagnetic compatibility and signal integrity studies. This algorithm allows the derivation of a rational approximation to the transfer matrix of a given linear structure starting from ...

Statistical modeling of frequency responses using linear Bayesian vector fitting [PDF]

open access: yes, 2020
This article presents a Bayesian extension of the vector fitting (VF) procedure for rational approximation of frequency-domain responses. The proposed method treats the linear part of VF in a Bayesian way, while propagating distributions through the ...

Fast computation of the nonlocal boundary condition in finite difference parabolic equation radiowave propagation simulations [PDF]

open access: yes, 2008
Finite difference parabolic equation method (FD-PEM) codes using a nonlocal boundary condition to model radiowave propagation over electrically large domains, require the computation of time consuming spatial convolution integrals. For the first time, we

A decade of vector fitting development: Applications on signal/power integrity [PDF]

open access: yes, 2010
Vector Fitting (VF) has been introduced as a partial-fraction basis response fitting methodology for over a decade. Because of its reliability and versatility, VF has been applied and extended to a number of areas.
