1. Towards Low-Voltage, High-Current : A pioneering drive concept for battery electric vehicles
Sammanfattning : The first electric low-voltage vehicles were constructed in the mid-19th century, but by the early 20th century they were progressively replacedby successors with internal combustion engines. As the consequences ofusing fossil fuels are better understood, our society is now transitioning back. LÄS MER
2. Reduction of voltage dips by redesign of an industrial distribution system using fast switches and current limiting devices
Sammanfattning : .... LÄS MER
3. Long-term Voltage Stability in Power Systems - Alleviating the Impact of Generator Current Limiters
Sammanfattning : The main issues in this dissertation are the behaviour of current limiters protecting synchronous generators, and the interactions that occur with other components in the power system during a voltage instability. The importance of these limiters for the voltage stability is shown both in the analysis of small models and in the simulations of larger networks. LÄS MER
4. On the fluid mechanics of electrochemical coating and spray painting
Sammanfattning : Finite-volume methods have been used for modeling of fluidflows involved in forced convection electrochemical coating androtating spray painting systems. Electrodeposition on a singlecircular cylinder under forced convection for Reynolds numbers10 and 200 was simulated. LÄS MER
5. Limiting processes in anion-exchange membrane fuel cells
Sammanfattning : Fuel cells allow for converting chemical energy stored in hydrogen into electrical energy, with only heat and water as by-products. In a sustainable energy society, hydrogen may play an important role due to its ability to act both as an energy carrier and as a valuable chemical in the process industry. LÄS MER
