Maximum current injection method for grid‐forming inverters in an islanded microgrid subject to short circuits

open access: yesIET Power Electronics, 2023
In islanded microgrids, when a short circuit or a sudden overload occurs, it provokes an abrupt increment in the currents supplied by the generation nodes, which feed the load collaboratively.

Combined PV-Wind Hosting Capacity Enhancement of a Hybrid AC/DC Distribution Network Using Reactive Control of Convertors and Demand Flexibility

open access: yes, 2022
The integration of Renewable Energy Sources (RESs) into distribution networks has increased in recent years due to numerous advantages. However, the RESs are intermittent and uncertain therefore may cause various limitations such as high lines loading ...

Multipulse improved-power-quality AC–DC convertors for vector-controlled induction-motor drives

open access: yes, 2006
The paper deals with polygon autotransformer-based 12-pulse and 18-pulse AC-DC convertors feeding vector-controlled induction-motor drives (VCIMDs) for improving power quality at the point of common coupling (PCC).

Hybrid space vector modulation for low‐order common‐mode voltage reduction in current‐source rectifier for transformerless medium voltage drives

open access: yesIET Power Electronics, 2023
For transformerless current‐fed medium voltage drives, low‐order harmonics of common‐mode voltages (CMVs) are more concerned with than peak values. To mitigate low‐order harmonics, the average values of CMVs should be suppressed.

Formulation of the energy-storage factor for isolated power convertors using integrated magnetics

open access: yes, 2005
The energy storage in energy-storage components is examined for isolated power convertors. In addition to the basic convertors such as the flyback and forward, the paper also develops the analysis for the various isolated versions of power convertors as ...

A single‐source switched‐capacitor based 13‐level sextuple boost inverter with reduced component count and low THD

open access: yesIET Generation, Transmission & Distribution, 2023
A switched‐capacitor‐based 13‐level inverter with a lesser number of components is presented in this article. The 13‐level single‐phase AC output voltage is achieved with a voltage gain of 6 by including a single DC source, 11 switches, 4 capacitors, and

Design and DC fault clearance of modified hybrid MMC with low proportion of full‐bridge submodules

open access: yesIET Generation, Transmission & Distribution, 2021
The hybrid modular multilevel converter (MMC) consisting of half bridge submodules (HBSMs) and full bridge submodules (FBSMs) combines the respective advantages of both submodules.

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

open access: yesFEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

open access: yesFEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...
