1. Closed-loop control and data- recording of a modular-multilevel converter (MMC)
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : 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. READ MORE

2. Analysis of Different Switching Patterns to Minimize Losses in a Six- Phase Drive for Marine Application
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : Multiphase machines have gained a lot of popularity during the recent years, as they offer certain benefits over their three- phase counterparts. This work investigates the losses of a six- phase drive system for a marine application when supplied by four different switching patterns (also referred to as modulators). READ MORE

3. Integrating Wind Power into The Electric Grid : Predictive Current Control Implementation
University essay from Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)Abstract : The increasing penetration of wind power into the power system dominated by variable-speed wind turbines among the installed wind turbines will require further development of control methods. Power electronic converters are widely used to improve power quality in conjunction with the integration of variable speed wind turbines into the grid. READ MORE

4. Analysis of harmonic cross-modulation in HVDC line-commutated converters for practical design purposes
University essay from Högskolan Väst/Avdelningen för Industriell ekonomi, Elektro- och MaskinteknikAbstract : The use of HVDC has many benefits over HVAC for some specific power transmission purposes. However, two major problems with HVDC links are that the converters produce harmonics and consume reactive power. Electrical filters are used to compensate for this and are a major cost driver of HVDC links. READ MORE

5. Automatically measuring the losses of a transformer
University essay from Blekinge Tekniska Högskola/Institutionen för signalbehandlingAbstract : This thesis is an ongoing project of Alstom Power Sweden AB, Växjö with a collaboration of Blekinge Institute of Technology [BTH] to automatically measure the losses of a transformer. So far the company performed the measurements manually to get this loss, and they decided to automatize the measurement process. READ MORE
