<span lang="EN-US">The proposed scheme is employed for the efficient operation of a DC-DC-based buck converter. This protection shows optimal placement varistor in power electronics converter side under different surge conditions. Advanced varistors have excellent electrical material properties and electrothermal behavior enhancement absorption capability. Varistors been examined widely l...

Overhead distribution lines are prone to lightning overvoltages due to their configurations and characteristics. Metal Oxide Varistor (MOVs) arresters for many years have proven to be more advantageous than others arresters in lightning surge protection; therefore it is worthwhile to continually assess the behavior and performance of these arresters to different kind of overvoltages caused by l...

The Zn–Bi–O films were deposited by reactive radio frequency magnetron sputtering in oxygen atmosphere from ZnBi alloy target (wt% ratio Zn:Bi=9:1) on glass substrate at room temperature. The XRD patterns show that the films deposited on tin-doped indium oxide/glass substrates were nanocrystalline. The microstructure of Bi-doped ZnO films was studied by scanning electron microscopy in combinati...

Rutile-TiO2 ceramics are very promising electronic ceramic materials which can be applied in varistors because of their good electrical properties. In this work, Dy2O3 was used to improve the properties a TiO2 varistor doped with 0.60 mol.% Nb2O5 and 0.30 SiO2. Results showed that possessed optimal nonlinear coefficient ( $$ \alpha = 5.7 ), low breakdown voltage E_{\text{B}} 1.34\;{\text{V}}\,{...

By applying the nonequilibrium Green's functions and the density-functional theory, we investigate the electronic structures and transport properties of fluorinated zigzag-edged boron nitride nanoribbons. The results show that the transition between half-metal and semiconductor in zigzag-edged boron nitride nanoribbons can be realized by fluorination at different sites or by the change of the f...
