Stabilized Control for Power Electronics Transformer-Based Grid-Tied Inverter System
IEEE Access, 2023 The stability of a grid-tied inverter system will be compromised in weak grid conditions. In order to address this problem, researchers have proposed using a power electronics transformer (PET) to connect inverters and the grid.

Impedance analysis of new PS internal dump design [PDF]
, 2018 The High Luminosity Large Hadron Collider (HL-LHC) project at CERN calls for increasing beam intensity in the injector chain. In the Proton Synchrotron (PS), a pre-injector of the LHC, these intensities can result in beam instabilities and potential RF ...

A Generalized Input Impedance Model of Multiple Active Bridge Converter
IEEE Transactions on Transportation Electrification, 2020 The electrical power distribution system (EPDS) of the more electric aircraft (MEA) is a fundamental component that needs to be efficient and resilient. The commonly considered architectures feature separate buses to achieve separation between different ...

On the modeling of sound propagation over multi-impedance discontinuities using a semiempirical diffraction formulation [PDF]
, 2006 Several approximate extensions of the semi-empirical De Jong model [ De Jong et al., J. Sound and Vib. 86, 23–46 (1983) ] are considered for the prediction of sound propagation over multiple impedance discontinuities.

Modeling electrochemical impedance spectroscopy [PDF]
Current Opinion in Electrochemistry, 2019 Abstract Electrochemical impedance spectroscopy (EIS) is a powerful technique that is used for characterizing electrochemical systems. The EIS data can be correlated with many key physical properties, including rates of diffusion and reaction, and microstructural features.

New combined model of high impedance arcing fault in overhead transmission system [PDF]
, 2012 High impedance fault is a popular complex phenomenon that exhibits high nonlinear behavior. For most distinctive characteristics of high impedance fault, are asymmetry and nonlinearity, so, in order to obtain an accurate model of high impedance fault, it
