Model predictive control for Active-Bridge-Active-Clamp (ABAC) converter [PDF]

, 2018
The Dual-Active-Bridge is a well-established isolated, bidirectional DC/DC topology suitable for applications where high efficiency, galvanic isolation and large voltage conversion ratios are required. However, in low voltage high power cases, the output

Geometry optimization and characterization of three-phase medium frequency transformer for 10kVA isolated DC-DC converter [PDF]

, 2017
Three-phase Dual Active Bridge converter is advisable for the High-power DC-DC conversion system. In the ac link, galvanically isolated transformer operated at a medium frequency range provides stepping up or down of the secondary bridge voltage. This

A methionine‐lined active site governs carbocation stabilization and product specificity in a bacterial terpene synthase

FEBS Letters, EarlyView.
This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

An Analysis of a Transformerless Dual Active Half-Bridge Converter

Power Electronics and Drives, 2022
This paper proposes a transformerless dual half-bridge converter (TLDAHB). By eliminating the transformer and harnessing the possibility of using a low inductor value, it is possible to minimise the size of the converter.

Reactive Power Controller for Single Phase Dual Active Bridge DC–DC Converters

IEEE Access, 2023
In this study, we have proposed a triple-phase shift power-level controller (TPSPC) that achieves zero reactive power generation by fundamental components in a single-phase dual active bridge (DAB) DC-DC converter.

Raman‐based label‐free microscopic analysis of the pancreas in living zebrafish larvae

FEBS Open Bio, EarlyView.
Forward stimulated Raman scattering (F‐SRS) and epi coherent anti‐Stokes Raman scattering (E‐CARS) allow label‐free discrimination of distinct subcellular structures in the pancreas of living zebrafish larvae. Given the straightforward applicability, we anticipate broad implementation of Raman microscopy in other organs and across various biomedical ...

Design and Optimization of Current-Fed Dual Active Bridge Converter with Dual Coupled-Inductor Structure

Energies
In order to reduce magnetic components for a current-fed dual active bridge converter, this paper proposes a dual coupled-inductor (DCI) structure, which integrates two DC inductors, one high-frequency transformer, and one leakage inductor into two EE ...

CX3CL1 in Early Detection of Alzheimer's Disease: Plasma Dynamics Across Age and Disease Stages

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Backgrounds Alzheimer's disease (AD) is characterized by amyloid‐beta plaques, tau tangles, and neuroinflammation. C‐X3‐C motif chemokine ligand 1 (CX3CL1, also known as fractalkine), a neuroimmune chemokine implicated in AD pathogenesis, shows inconsistent alterations in plasma/serum across studies.
