A Three-Level dc-dc Converter for Bipolar dc Power Grids: Analysis and Experimental Validation [PDF]

IECON 2020 The 46th Annual Conference of the IEEE Industrial Electronics Society, 2020
The concept of bipolar dc power grids has emerged, mainly due to the improvements in efficiency and offered flexibility when compared with unipolar architectures. Though, concerns of asymmetrical loads affecting voltage unbalances is the key challenge to overcome.

Composites of Shellac and Silver Nanowires as Flexible, Biobased, and Corrosion‐Resistant Transparent Conductive Electrodes

Advanced Functional Materials, EarlyView.
Shellac, a centuries‐old natural resin, is reimagined as a green material for flexible electronics. When combined with silver nanowires, shellac films deliver transparency, conductivity, and stability against humidity. These results position shellac as a sustainable alternative to synthetic polymers for transparent conductors in next‐generation ...

Power Flow Controller for The Meshed DC Grids [PDF]

Advances in Engineering Research, 2015
With more and more environmental problems, renewable energy begins to play an increasingly large proportion. High-voltage direct current technology based on voltage source converter (VSC-HVDC) enables smooth access to renewable energy. Traditional DC grids system is generally radial connections, but In recent years, there are many parallel lines ...

Intermediate Resistive State in Wafer‐Scale Vertical MoS2 Memristors Through Lateral Silver Filament Growth for Artificial Synapse Applications

Advanced Functional Materials, EarlyView.
In MOCVD MoS2 memristors, a current compliance‐regulated Ag filament mechanism is revealed. The filament ruptures spontaneously during volatile switching, while subsequent growth proceeds vertically through the MoS2 layers and then laterally along the van der Waals gaps during nonvolatile switching.
