On the use of Cramér-Rao Lower Bound for least-variance circuit parameters identification of Li-ion cells

Mario Paolone, Vladimir Sovljanski

Electrochemical Impedance Spectroscopy (EIS) and Equivalent Circuit Models (ECMs) are widely used to characterize the impedance and estimate parameters of electrochemical systems such as batteries. We use a generic ECM with ten parameters grouped to model ...

Impact of beam-coupling impedance on the Schottky spectrum of bunched beam

Tatiana Pieloni, Nicolas Frank Mounet, Christophe Emmanuel R. Lannoy

The Schottky monitors of the Large Hadron Collider (LHC) can be used for non-invasive beam diagnostics to estimate various bunch characteristics, such as tune, chromaticity, bunch profile or synchrotron frequency distribution. However, collective effects, ...

Iop Publishing Ltd2024

This article proposes a new two-wired amplifying active electrode (AE), presenting a high input impedance and a high common-mode rejection ratio (CMRR). In the proposed structure, the input impedance and the CMRR of the system are considerably increased by ...

Piscataway2024

This paper presents a novel impedance-sensing device and its related microfluidics system developed to characterize the macroscopical properties of bacteria and microparticles. The system is based on a phase-sensitive detector with square-waves excitation ...

IEEE2022

The safe and reliable operation of modern power system imposes the need to describe and estimate the system stability through impedance-admittance measurement and identification. The integration and operation of medium voltage equipment in existing infrast ...

Single-Phase Measurement of the Output Impedance of the Four-Quadrant Cascaded H-Bridge Converter Cell Using Wideband Signals

Drazen Dujic, Marko Petkovic

The development and integration of power electronics equipment and converters for medium voltage ac and dc application has created different subsystem interactions that require proper investigation, understanding, description and estimation of global syste ...

On the Differential Input Impedance of an Electro-Explosive Device

Abstract: In this paper, a model for the input impedance of a hot-wire electro-explosive device (EED) based on differential-mode measurements is proposed. The model represents the EED using three transmission line segments in cascade. The characteristics o ...

An Approch for the Emulation of DC Grid Admittances: Implementation an a Buck Converter

Drazen Dujic, Francisco Daniel Freijedo Fernández, Enrique Rodriguez Diaz

This work proposes a method to actively emulate dc grids, including their equivalent admittance, by means of a modified current control structure of a dc/dc converter. The stability of power converter units (PCUs), interconnected with electrical grids is f ...
