Control Strategies for the DAB Based PV Interface System. [PDF]

PLoS ONE, 2016
This paper presents an interface system based on the Dual Active Bridge (DAB) converter for Photovoltaic (PV) arrays. Two control strategies are proposed for the DAB converter to harvest the maximum power from the PV array. The first strategy is based on

High Step-Down Isolated PWM DC–DC Converter Based on Combining a Forward Converter With the Series-Capacitor Structure

IEEE Access, 2023
Incorporating switched-capacitor structures into isolated dc-dc converters is a promising approach to alleviate the limitations of topologies fully based on the use of high step-down transformers.

ACL command with forward converter [PDF]

, 2009
Objectif: Les ACL sont des lampes 28V/250W utilisées dans le domaine de l’éclairage scénique. Jusqu’à présent 8 lampes sont branchées en série sur le réseau ce qui interdit toute commande individuelle. L’appareil conçu dans ce projet contient un « Power Factor Corrector PFC » pour pouvoir créer un bus de tension à 400V et un convertisseur de type ...

Genetic attenuation of ALDH1A1 increases metastatic potential and aggressiveness in colorectal cancer

Molecular Oncology, EarlyView.
Aldehyde dehydrogenase 1A1 (ALDH1A1) is a cancer stem cell marker in several malignancies. We established a novel epithelial cell line from rectal adenocarcinoma with unique overexpression of this enzyme. Genetic attenuation of ALDH1A1 led to increased invasive capacity and metastatic potential, the inhibition of proliferation activity, and ultimately ...

IMPDH inhibition enhances cytarabine efficacy in SAMHD1‐expressing leukaemia cells via guanine nucleotide depletion

Molecular Oncology, EarlyView.
Cytarabine is a key therapy for acute myeloid leukaemia (AML), but its efficacy is limited by the dNTPase SAMHD1, which hydrolyses its active metabolite. Screening nucleotide biosynthesis inhibitors revealed that IMPDH inhibitors selectively sensitise SAMHD1‐proficient AML cells to cytarabine.

A new forward‐flyback converter without right half plane zero

IET Power Electronics
Due to its unique features, the flyback converter is widely used to convert DC to DC power. This converter has a non‐minimum phase (NMP) dynamic behavior, which is one of its most significant disadvantages.

Dual-switch forward converter with an additional reset capacitor for hold-up operation

The Journal of Engineering, 2019
An improved scheme of a dual-switch forward converter is proposed in this paper. Compared with the original converter, the new one can provide higher resetting voltage during the hold-up time interval under the action of an additional reset capacitor ...

Rethinking plastic waste: innovations in enzymatic breakdown of oil‐based polyesters and bioplastics

FEBS Open Bio, EarlyView.
Plastic pollution remains a critical environmental challenge, and current mechanical and chemical recycling methods are insufficient to achieve a fully circular economy. This review highlights recent breakthroughs in the enzymatic depolymerization of both oil‐derived polyesters and bioplastics, including high‐throughput protein engineering, de novo ...

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 ...

A New Feed-Forward Control for Dynamics Improvement in a Dual-Input DC–DC Converter for Hybrid Vehicle Applications

Energies
In this study, a double-input single-output bidirectional DC–DC converter is considered. This particular architecture allows less switches to be used than a conventional solution.
