1. 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
2. Battery Balancing on a Full-Bridge Modular Multi-Level Converter
Master-uppsats, Linköpings universitet/FordonssystemSammanfattning : Batteries are becoming popular in the trend of electrification. Performance andlifespan of a battery pack are closely related to how it has been utilized. Withproper balancing control to slow down aging process, variances of capacity andresistance between battery cells can be maintained at a better level. LÄS MER
3. Comparative Analysis of Several Designs of Modular Multilevel Converters with Interleaved Half-Bridge Submodules
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : The Modular Multilevel Converter (MMC) is one of the most commonly used active converters in the high-/medium-voltage sector due to its many advantages such as high scalability, high efficiency, modularity and low harmonic contents. However, in low-voltage and high-current applications, classical MMC designs are not very economical. LÄS MER
4. Evaluation of DC Fault Current in Grid Connected Converters in HVDC Stations
Master-uppsats, Uppsala universitet/Institutionen för elektroteknikSammanfattning : The main circuit equipment in an HVDC station must be rated for continuous operation as well as for stresses during ground faults and other short circuits. The component impedances are thus selected for proper operation during both continuous operation and short circuit events. LÄS MER
5. Power Electronic Enhanced Distribution Transformer : Seamless Voltage Regulation with Extended Functionalities
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : On-load tap changers and static synchronous compensators (STATCOM) are the main components for voltage regulation and power quality optimization in the power system. STATCOMs are used in both industrial applications and utility to stabilize the grid and reduce downtime. LÄS MER
