Mixed-Criticality systems are arising due to the push from several major industries including avionics and automotive, where functionalities with different safety criticality levels are integrated into a modern computing platform to reduce size, weight and energy. The state-of-the-art research has focused on protecting critical tasks under the threat of task overrun, which is achieved by […]

This paper investigates the Gallium Nitride (GaN) devices benefits on the LLC resonant DC-DC converter. First, the relationship between the device parameters and converter current based on an analytical loss model of LLC resonant converter has been established. After that, the loss analysis and comparison between Si-based and GaN-based converter is presented. The GaN-based design […]

An analytical method is employed to characterize the reactive power loss of a single-phase transformer when subjected to geomagnetically induced current (GIC). A general closed-form formula is proposed to calculate the reactive power loss of the transformer as a function of the applied voltage, air-core inductance, and GIC. The developed equation reveals that the reactive […]

For the past decade, there has been an increase in the frequency and impact of natural disasters. Information and communications technology (ICT) can be used to minimize the impact of disasters in many ways. However, before deployment, disaster-related ICT systems need to be tested and validated using the appropriate modeling and simulation tools. In this […]
