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.

IET Systems Biology, 2020 The skin is a complex biological tissue whose impedance varies with frequency. The properties and structure of skin changes with the location on the body, age, geographical location and other factors. Considering these factors, skin impedance analysis is a sophisticated data analysis.

Effective impedance modeling of metamaterial structures [PDF]
Journal of the Optical Society of America A, 2016 We present methods for retrieving the effective impedance of metamaterials from the Fresnel reflection coefficients at the interface between two semi-infinite media. The derivation involves the projection of rigorous modal expansions onto the dominant modes of the two semi-infinite media.

A comparison of impedance boundary conditions for flow acoustics [PDF]
, 2013 Acoustic liners remain a key technology for reducing community noise from aircraft engines. The choice of optimal impedance relies heavily on the modeling of sound absorption by liners under grazing flows.

Automatic compensation system for impedance measurement [PDF]
, 2002 This paper deals with the realization of the four-pair terminal definition of impedance standards. A simple, though reliable, system is described that allows an automatic compensation of the voltage at the low potential port of impedance standards to be ...
