Improved Quasi-Z-Source High Step-Up DC–DC Converter Based on Voltage-Doubler Topology
Sensors, 2022 The step-up DC–DC converter is widely used for applications such as IoT sensor nodes, energy harvesting, and photovoltaic (PV) systems. In this article, a new topological quasi-Z-source (QZ) high step-up DC–DC converter for the PV system is proposed. The

Development of Fractional Order Modeling of Voltage Source Converters [PDF]
IEEE Access, 2020 This paper proposes a mathematical fractional order modelling of Voltage Source Converters (VSC). Fractional behaviour helps to model and describe a real object more accurately than the integer order model. State-space equations of VSC is obtained using fractional calculus in d-q domain.

Tuning of Cascaded Controllers for Robust Grid-Forming Voltage Source Converter
Power Systems Computation Conference, 2018 From the origin of the grid, energy has been delivered to electrical loads mainly by synchronous machines. All the main rules to manage the grid have been based on the electromechanical behavior of these machines which have been extensively studied for ...

Stabilization of Electrical Parameters of Machine-Converter Voltage Source [PDF]
EAI Endorsed Transactions on Energy Web, 2018 The paper is devoted to development of Machine-Converter Source (MCS), which forms the output voltage waveform of electric generator as sum of EMFs with near frequencies. As electric modulation generator is used a synchronous generator and asynchronous exciter that have both common driving shaft and common housing.

FEBS 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 ...

Reciprocal control of viral infection and phosphoinositide dynamics
FEBS Letters, EarlyView.Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.
