Comparative feasibility study of partial power converter for interfacing battery energy storage into power system of future circular collider [PDF]

Proceedings of the Estonian Academy of Sciences
The recent appearance of partial power converters has shown their potential to significantly improve the efficiency and power density of power electronic systems. However, their feasibility in different applications is not sufficiently studied.

Single‐pole tripped emergency control and multistep power recovery strategy for a symmetric bipolar VSC‐HVDC system

IET Generation, Transmission & Distribution, 2022
In a symmetric bipolar voltage sourced converter‐high voltage direct current system (VSC‐HVDC) with a conventionally independent power controller, a single‐pole converter unit malfunction or conversion capacity limitation results in a power imbalance for

Power Converters Dominated Power Systems

, 2020
The transition to a low-carbon society is the driving force pushing the traditional power system to increase the volume of non-synchronous technologies which mainly use power electronic converters (PEC) as an interface to the power network. Today, PEC is found in many applications ranging from generation, transmission, storage, and even active loads ...

Power Performance Analysis According to the Configuration and Load Control Algorithm of Power Take-Off System for Oscillating Water Column Type Wave Energy Converters

Energies, 2020
A power take-off (PTO) system for an oscillating water column (OWC) wave energy converter comprises a turbine-generator-power converter. In this study, only the topologies of the power converter that affect the load control algorithm are compared.

A step-down nesting-type ac–ac converter combined with voltage equalizers and switched-capacitor simple converters

Energy Reports, 2020
In this paper, we present an inductor-less direct ac–ac converter with improved nesting-type topology. Unlike existing direct ac–ac converters, the proposed ac–ac converter combines a voltage equalizer and a switched-capacitor (SC) simple converter ...

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

By dawn or dusk—how circadian timing rewrites bacterial infection outcomes

FEBS Letters, EarlyView.
The circadian clock shapes immune function, yet its influence on infection outcomes is only beginning to be understood. This review highlights how circadian timing alters host responses to the bacterial pathogens Salmonella enterica, Listeria monocytogenes, and Streptococcus pneumoniae revealing that the effectiveness of immune defense depends not only

Interplay between circadian and other transcription factors—Implications for cycling transcriptome reprogramming

FEBS Letters, EarlyView.
This perspective highlights emerging insights into how the circadian transcription factor CLOCK:BMAL1 regulates chromatin architecture, cooperates with other transcription factors, and coordinates enhancer dynamics. We propose an updated framework for how circadian transcription factors operate within dynamic and multifactorial chromatin landscapes ...
