Quantitative stability analysis of Grid-Following inverter with Grid-Supporting control and stability enhancement method based on Multi-Voltage feedforward

International Journal of Electrical Power & Energy Systems
Grid-following inverters with grid-supporting control (GFLI-GSC) can provide inertia and voltage support to the grid, but GSC degrades their stability under weak grid.

Compact ultra‐wideband bandstop filter using capacitive loads

Electronics Letters, 2019
A compact UWB band‐stop filter (BSF) using capacitive loads is proposed. In contrast to its traditional counterparts, this proposed BSF only consists of two capacitors and a short‐ended coupled line (C‐section).

Oxygen Evolution Electrocatalysts with Trinuclear, Mixed‐Valence Iron Motifs on Electronically Aligned Carbon Dots

Advanced Functional Materials, EarlyView.
Trinuclear iron oxo‐bridged catalytic ensembles stabilized by aspartic‐acid‐derived carbon dots provide an effective platform for alkaline oxygen evolution. Mixed‐valence charge balancing, inner‐sphere charge transport, and work‐function alignment within the N/O‐rich carbon framework promote cooperative Fe‐site chemistry and efficient OER ...

Coupling Schemes in Terahertz Planar Metamaterials

International Journal of Optics, 2012
We present a review of the different coupling schemes in a planar array of terahertz metamaterials. The gap-to-gap near-field capacitive coupling between split-ring resonators in a unit cell leads to either blue shift or red shift of the fundamental ...

Ion‐Reconfigurable “N”‐Shaped Antiambipolar Behavior in Organic Electrochemical Transistors

Advanced Materials, EarlyView.
A unique N‐shaped negative differential transconductance (NDT) characteristics is demonstrated in single‐polymer organic electrochemical transistors through a sequential doping–redox–doping process driven by iodide ions. This redox‐driven mechanism enables low‐voltage, ion‐controlled reconfigurability and tunable current modulation, allowing seamless ...
