The reliability of AlGaN/GaN high electron mobility transistors (HEMTs) is traditionally determined via thermal lifetime acceleration stress tests. More recently it has been proposed that electric field has a prominent role in limiting lifetimes. ...
There is a need for a foundation of a research study aimed at investigations on near real-time reliability awareness of Gallium Nitride devices in high-frequency power converters for which we need advanced hardware and algorithms. This dissertatio...
Modern power and energy systems rely heavily on power electronics converters. The most significant component of these converters is the power semiconductor switching devices MOSFETs/IGBTs. Two critical parameters that provide real-time information...

Description
Wildfires are one of the main threats to overhead power lines worldwide, causing permanent damages and interruptions. Wildfires represent the second leading cause of outages in the Brazilian Interconnected Grid and the fourth leading cause in the ...
Safety is often understood as freedom from unacceptable loss; reliability as the capacity to accomplish particular outcomes repeatedly through operational sensitivity. Both compel performance objectives for high-risk organizations. If either is ab...
Using the Transactional Model of Stress and Coping as a guiding theoretical framework, the current investigation followed the steps of instrument development outlined by Crocker and Algina (2008). The purpose of this study was to examine the facto...
