1. Förlustanalys av Elnätdistribution i Eskilstuna : En noggrann undersökning av elförluster och dess konsekvenser i ett område i Eskilstuna
Uppsats för yrkesexamina på grundnivå, Mälardalens universitet/Akademin för ekonomi, samhälle och teknikSammanfattning : This thesis explores the losses occurring in a specific region located in the southern part of Eskilstuna, where ESEM serves as the network owner. The study places particular emphasis on power factor and load factor as key factors. Its objective is to analyze and comprehend the extent of losses in the network and their implications. LÄS MER
2. Design and Simulation of a 10kW High-Efficiency Dual Active Bridge Converter
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : The EU has proposed an ambitious goal to achieve widespread E-mobility in both the electrical and commercial sectors. To accomplish this, a substantial number of DC fast-charging stations must be built. LÄS MER
3. Closed-loop control and data- recording of a modular-multilevel converter (MMC)
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Modular multilevel converters (MMCs) are the preferred converter solution in flexible ac transmission systems (FACTS) and high-voltage direct current (HVDC) applications. This is due to the high quality of the voltage and current signals, lower overall losses, and fewer problems with switching-related EMI. LÄS MER
4. Development of an on-board charger model for real time simulation
Master-uppsats, KTH/Väg- och spårfordon samt konceptuell fordonsdesignSammanfattning : Electrification of vehicles is now one of the top priorities of automotive manufacturers in orderto comply with the sustainability goals and standards set by the United Nations. One of thedisadvantages faced by electric vehicles is a longer time required for charging the vehicles ascompared to refuelling a conventional vehicle. LÄS MER
5. Optimization of battery pack assembly of second life cells to reduce costs
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : Batteries account for 50% of the overall cost of solar home systems (SHS). The battery packs degrade over time and when they reach 70% state of health (SOH), the whole SHS is discarded. In the predominantly rural off-grid context, battery replacements are expensive and impractical. The customers are often dozens of km away from any sales point. LÄS MER
