Highly-Reliable Switched-Boost Four-Leg Inverter With Leakage Current Suppression

IEEE Access
In this paper, a new switched-boost four-leg inverter is proposed to suppress the leakage current and provide high reliability. The proposed inverter provides full shoot-through immunity by replacing the active switch in the impedance-source network to ...

Ferroelectricity in Antiferromagnetic Wurtzite Nitrides

Advanced Functional Materials, EarlyView.
We establish MnSiN2${\rm MnSiN}_2$ and MnGeN2${\rm MnGeN}_2$ as aristotypes of a new multiferroic wurtzite family that simultaneously exhibits ferroelectricity and antiferromagnetism with altermagnetic spin splitting. By strategically substituting alkaline‐earth metals, we predict new materials with coexisting switchable polarization, spin texture, and

Copper‐Based Crystalline‐Metallic Glass Composite Thin Films: A Novel Material with Enhanced Strength and Thermally Stable Nanotwins

Advanced Functional Materials, EarlyView.
A Cu‐based crystal‐glass composite with high‐density twins is identified by a fast screening technique using combinatorial sputtering together with XRD and nanoindentation mapping. This bamboo‐like structure demonstrates homogenous plastic flow and retains high strength during in situ high temperature tests, up to 1 GPa at 550°C, owing to those ...

The PS 10 MHz High Level RF System Upgrade [PDF]

, 2016
In view of the upgrade of the injectors for the High Luminosity LHC, significantly higher bunch intensity is required for LHC-type beams. In this context an upgrade of the main accelerating RF system of the Proton Synchrotron (PS) is necessary, aiming at

Space vector pulse width modulation techniques for a five-phase impedeance source and quazi impedeance source inverters

2015 IEEE International Conference on Industrial Technology (ICIT), 2015
. Impedance source inverter (ZSI) and its variant quasi impedance source inverter (qZSI) are single stage inverters that transform dc to ac and boost the source voltage at the same time. These topologies have attracted great attention of researchers in recent times. This paper proposes space vector pulse width modulation (SVM) techniques to control ZSI

Scalable Polyelectrolyte Complex‐Based Sorbent With Hourly Sorption−Desorption Cycles for Multicyclic Atmospheric Water Harvesting in Arid Environments

Advanced Functional Materials, EarlyView.
A polyelectrolyte complex‐based sorbent is produced by scalable, environmentally benign aqueous phase inversion. Its porous, LiCl‐ and GO‐integrated architecture enables hourly adsorption−desorption cycles at low relative humidity (RH < 30%). A large‐scale prototype achieves multicyclic, solar‐driven atmospheric water harvesting of 1.37 L kg−1 day−1 ...

Improved design of passive damping for single phase grid‐connected LCL filtered inverter considering impedance stability

IET Power Electronics
Grid‐connected inverters with an inductor–capacitor–inductor (LCL) filter usually require the implementation of damping in the filter to suppress the resonance associated with the filter and hence ensure internal stability.
