AbstractIn this work, the effect of elevated temperature on the generated defects with constant voltage stress (CVS) in SiO2 and SiO2/HfSiO stacks is investigated. Applying Trap Spectroscopy by Charge Injection and Sensing (TSCIS) to 6.5 nm SiO2 layers, different kinds of generated traps are profiled at low and high temperature. Also the Stress-Induced Leakage Current (SILC) spectrum of high-k dielectric stack is different at elevated temperature indicating that degradation and breakdown at high temperature is not equivalent to that at low temperature and therefore, extrapolation of data from high to low T or vice versa is challenging.

Boost Control

This paper proposes maximum boost control for 7-level z-source cascaded h-bridge inverter and their affiliation between voltage boost gain and modulation index. Z-source network avoids the usage of external dc-dc boost converter and improves output voltage with minimised harmonic content. Z-source network utilises distinctive LC impedance combination with 7-level cascaded inverter and it conquers the conventional voltage source inverter. The maximum boost controller furnishes voltage boost and maintain constant voltage stress across power switches, which provides better output voltage with variation of duty cycles. Single phase 7-level z-source cascaded inverter simulated using matlab/simulink.
