1. Enhanced Active Resonant DC Circuit Breakers for HVDC Grids
Sammanfattning : High-voltage DC (HVDC) grids are considered promising for the electricity grid expansion required to integrate renewable energy sources into the existing infrastructure. DC fault currents increase rapidly and lack a current zero crossing. LÄS MER
2. Core Switching Noise for On-Chip 3D Power Distribution Networks
Sammanfattning : Reducing the interconnect size with each technology node and increasing speed with each generation increases IR-drop and Ldi/dt noise. In addition to this, the drive for more integration increases the average current requirement for modern ULSI design. LÄS MER
3. High Temperature Bipolar SiC Power Integrated Circuits
Sammanfattning : In the recent decade, integrated electronics in wide bandgap semiconductor technologies such as Gallium Nitride (GaN) and Silicon Carbide (SiC) have been shown to be viable candidates in extreme environments (e.g high-temperature and high radiation). Such electronics have applications in down-hole drilling, automobile-, air- and space- industries. LÄS MER
4. Model Based Vehicle Level Diagnosis for Hybrid Electric Vehicles
Sammanfattning : When hybridizing a vehicle, new components are added that need to be monitored due to safety and legislative demands. Diagnostic aspects due to powertrain hybridization are investigated, such as that there are more mode switches in the hybrid powertrain compared to a conventional powertrain, and that there is a freedom in choosing operating points of the components in the powertrain via the overall energy management and still fulfill the driver torque request.
