A new topology of the switched-inductor/capacitor quasi Z-source inverter with ability of uplifted-boost [PDF]

International Journal of Industrial Electronics, Control and Optimization, 2020
In this paper, a new topology of switched-inductor/capacitor quasi impedance source inverter is suggested, which in comparison with the other topologies possesses higher boost voltage inversion at high modulation index and low shoot through duty cycle ...

An adaptive virtual impedance fault current limiter for optimal protection coordination of islanded microgrids

IET Renewable Power Generation, 2022
Fault currents of inverter‐interfaced distributed generators (IIDGs) depend on inverter controllers. Thus, IIDGs fault currents are different than those of synchronous‐based DGs, both from the magnitude and waveshape perspectives.

Master–slave current regulation of an LCL-filter-based grid-connected inverter under variable grid condition

The Journal of Engineering, 2019
To ease the heavy burden of inverter control, including line current regulation, harmonic current suppression, filter resonance suppression, grid distortion suppression, phase locked loop etc., the study proposes a master–slave current regulation method ...

Fault-Tolerant Operation of an Open-End Winding Five-Phase PMSM Drive with Inverter Faults [PDF]

, 2013
The authors would like to thank the ADEME for the funding of the MHYGALE project.Multi-phase machines are known for their fault-tolerant capability. However, star-connected machines have no fault tolerance to inverter switch short-circuit fault.

Research on Dynamic Performance Improvement of Load Switching in Microgrid to Three-phase Voltage Source Inverter Based on LADRC

, 2020
The droop-controlled inverter can be modeled as a controllable voltage source with output impedance in series. However, dynamic performance in islanded microgrid mode is highly sensitive to the inverter output impedance.

Dimethyl fumarate combined with cisplatin at subcytotoxic doses sensitizes cervical cancer toward ferroptosis and apoptosis through GSH restriction and p53 (re)activation

Molecular Oncology, EarlyView.
Dimethyl fumarate (DMF) reduces growth of HPV‐positive cervical cancer spheroids and induces ferroptosis in cervical cancer cells via blocking SLC7A11/Glutathione (GSH) axis. Combination of subcytotoxic doses of DMF and cisplatin (CDDP) further suppresses spheroid growth and drives cell death in 2D culture models.

Power quality improvement by using photovoltaic based shunt active harmonic filter with Z-source inverter converter

Electrical engineering & Electromechanics, 2022
Introduction. The major source of energy for a long time has been fossil fuels, however this has its drawbacks because of their scarcity, exhaustibility, and impossibility of reusing them.
