1. Increasing Energy Efficiency in Electric Trains Operation : Driver Advisory Systems and Energy Storage
Sammanfattning : Electric traction is the most efficient traction system in the railway transportation. However, due to the expensive infrastructure and high power demand from the grid, the share of electric trains in the railway transportation is still lower than other trains. LÄS MER
2. Design, Modelling and Verification of Distributed Electric Drivetrain
Sammanfattning : The electric drivetrain in a battery electric vehicle (BEVs) consists of an electric machine, an inverter, and a transmission. The drivetrain topology of available BEVs, e.g., Nissan Leaf, is centralized with a single electric drivetrain used to propel the vehicle. LÄS MER
3. Inverter Design for SiC-based Electric Drive Systems with Optimal Redundant States Control of Space Vector Modulation
Sammanfattning : The need for inverters with ever increasing power density and efficiency has recently become the driving factor for research in various fields. Increasing the operating voltage of the whole drive system and utilizing newly developed SiC power switches can contribute towards this goal. LÄS MER
4. Safe Distributed Control Allocation for Articulated Heavy Vehicles
Sammanfattning : The electrification of trucks is now followed by the electrification of trailers. Additionally, the maximum allowed length of vehicle combinations has been increased in many countries to enhance efficiency. LÄS MER
5. On Deep Machine Learning Based Techniques for Electric Power Systems
Sammanfattning : This thesis provides deep machine learning-based solutions to real-time mitigation of power quality disturbances such as flicker, voltage dips, frequency deviations, harmonics, and interharmonics using active power filters (APF). In an APF the processing delays reduce the performance when the disturbance to be mitigated is tima varying. LÄS MER
