This study developed a novel, high-efficiency, high step-up DC–DC converter for photovoltaic (PV) systems. The can the low output voltage of PV modules to level inverter and is used feed into grid. achieve through its architecture consisting three-winding coupled inductor common iron core on low-voltage side half-wave doubler circuit high-voltage side. leakage inductance energy generated by cou...

We show that the concentration of oxygen interstitials trapped in Sc2O3 films by ion beam sputtering from metal targets can be controlled by modifying deposition conditions. We have identified point defects in the form of oxygen interstitials that are present in Sc2O3 films, in significantly high concentrations, i.e., ∼10(18)  cm(-3). These results show a correlation between the increase of oxy...

I. Introduction By reducing the gate-oxide thickness (T OX), the proportion of injected tunneling carriers increases during stress so that MOSFET's parameters are slightly changed. In thicker oxides (T OX >3.5nm), Stress Induced Leakage Current (SILC) was a good marker of oxide degradation. In thinner oxide, gate oxide leakage current appears in depletion regime, SILC is recalled as Low Voltage...
