Active Damping Method for LC-DAB System Based on a Power-Based Impedance Model
IEEE transactions on power electronics, 2023A cascaded system, consisting of an LC filter and a dual active bridge (DAB), can exhibit certain instability due to terminal impedance mismatch. In this regard, the existing impedance models of DAB are not convenient for designing the active damping ...

IEEE transactions on energy conversion, 2021
Impedance modeling of a permanent magnet synchronous generator (PMSG)-based wind energy conversion system (WECS) usually ignores the machine-side dynamics, instead, the machine-side system is simplified as a constant power source, while merely keeping ...

Stability analysis of the point-to-point high-voltage dc (HVdc) transmission systems is crucial for planning and operational purposes. However, due to the protection of trade secret and user privacy, it is difficult to have access to detailed information

This paper presents our work in the search for a realistic thorax impedance model that is suitable for the simulation of an impedance cardiography (ICG) signal model. The developed ICG signal model would be useful to evaluate the performance of e.g. algorithms for the separation of cardiac and respiratory signals. Five different impedance models of the

Harmonic Stability Analysis of MMC-Based DC System Using DC Impedance Model
IEEE Journal of Emerging and Selected Topics in Power Electronics, 2020The dc impedance model of a modular multilevel converter (MMC) is the basis for analyzing harmonic resonances of MMC-based dc systems. As an MMC typifies a multiple harmonic response system, its internal dynamics and controls significantly influence its ...

The Impedance of Curved Artery Models
Journal of Biomechanical Engineering, 1983The impedance (pressure drop/flow rate) of four curved artery models has been determined experimentally for steady and periodic flows simulating conditions in the aortic arch. Steady flow results indicate that very short entry lengths are required for flow development in curved artery models, and impedance is elevated above straight tube values by a ...
