Wideband Dissipativity Enhancement for Multi-Sampling Controlled Grid-Following VSCs

, 2022
With the gradually decreasing cost of high-performance digital processors, multi-sampling current control is a promising method to reduce the control delay and improve the high-frequency dissipativity in grid-connected converters. Specifically, with the capacitor voltage feedforward and the inverter-side current feedback, the dissipation of the multi ...

Spatially Modulated Morphotropic Phase Boundaries in a Compressively Strained Multiferroic Thin Film

Advanced Functional Materials, EarlyView.
ABSTRACT The coexisting rhombohedral‐like (R′, MA) and tetragonal‐like (T′, MC) monoclinic phases in compressively strained bismuth ferrite thin films exhibit exceptional piezoelectric and magnetic properties. While previous studies have largely focused on probing the morphotropic phase boundaries (MPBs) comprising ordered R′/T′ twins, their self ...

Exploring an Alternative to mRNA Vaccine Cold Chain Storage: MRNA‐Lipid Nanoparticle Stability When Dried in a Polymer Matrix

Advanced Functional Materials, EarlyView.
The nanostructure, size, and function of mRNA‐loaded lipid nanoparticles are evaluated before drying, within polymer microneedles, and after rehydration. The results reveal the polymer and LNP loadings required to recover nanostructure and preserve the delivery performance in dry‐state formulations.

Robust control of grid-connected converters under wide grid impedance variation

, 2019
This paper investigates the robust current control of grid-connected converters operating under wide grid impedance variation. Digital state feedback control gains are obtained based on linear matrix inequalities that ensure the location of the closed ...

Electrode and Microstructure Dependence of Oxygen Diffusion in Ferroelectric Hafnium Zirconium Oxide Thin Films

Advanced Functional Materials, EarlyView.
Significant nanoscale oxygen diffusion coefficient variations are measured in ferroelectric hafnium zirconium oxide films with grain boundaries and electrode interfaces exhibiting values 104 times larger than the grain cores. Overall coefficients are 10X larger for films prepared with metal nitride electrodes compared to refractory metals. New insights

Analysis of transient characteristics and fault ride-through control of hybrid grid-tied converters with grid-following and grid-forming

Frontiers in Energy Research
When the Grid-Following (GFL) and the Grid-Forming (GFM) converters are hybrid-connected to the grid, they are coupled through the grid impedance. During grid faults, the transient characteristics of the two converters become more complex due to this ...
