1. Aspects on Wind Turbine Protections and Induction Machine Fault Current Prediction
Sammanfattning : This thesis presents detailed modelling of the induction machine with the main objective being accurate fault current prediction. The thesis focus mainly on mains connected induction machines and the response due to severe disturbances in the supply voltage, such as three-phase short-circuit faults. LÄS MER
2. Design of a fault-tolerant fractional slot PMSM for a vehicle application
Sammanfattning : In automotive applications, the PMSM is an interesting alternative due to the high efficiency requirement; as only a limited amount of energy can be stored in the relatively expensive battery. Another advantage is the high torque and power density since it is very important to save especially space but also weight in vehicle applications. LÄS MER
3. Advancing Upconversion Emissions for Biomedical Imaging
Sammanfattning : During the past decade, upconverting nanoparticles (UCNPs) doped with rare earth ions have become an important class of fluorescence contrast agents for molecular imaging, due to their unique properties. Their property of anti-Stokes luminescence, with both the excitation and emission wavelengths close to the optimal for biomedical imaging, has been extensively explored in various biomedical applications.

4. Design and analysis of a fault-tolerant fractional slot PMSM for a vehicle application
Sammanfattning : The permanent magnet synchronous motor (PMSM) is an interesting alternative for an electric motor drive system in automotive applications, due to to the high efficiency requirement; as only a limited amount of energy can be stored in the relatively expensive battery. Another advantage is the high torque and power density a PMSM can achieve since it is very important to save especially space but also weight in vehicle applications. LÄS MER
5. On Power-system Benefits, Main-circuit Design, and Control of StatComs with Energy Storage
Sammanfattning : Static synchronous compensation (StatCom) is an application that utilizes a voltage source converter (VSC) to provide instantaneous reactive power support to the connected power system. Conventionally, StatComs are employed for reactive power support only. LÄS MER
