Review of Current control strategies in Modular Multilevel Converter
Wei, Jianzhao (Master thesis, 2016)With the rapid development of offshore wind farms, the demand for high power, high quality transmission system becomes more urgent. Modular Multilevel converter (MMC) based high voltage direct voltage (HVDC) technology ... -
Sensorless Control of Permanent Magnet Synchronous Machines - Derivation and Implementation
Haustveit, Eirik (Master thesis, 2016)This master project is a further investigation of the topics covered in the specializa- tion project Laboratory platform for PM machine drive study - Adaptive Torque Estimation . Permanent magnet synchronous machines ... -
Simulation, design and implementation of permanent magnet motor drive
Tilset, Jon Inge Moe (Master thesis, 2015)Abstract This study presents the design of a Permanent Magnet Synchronous Motor (PMSM) and its drive system. In order to design the drive, an extensive literature study on PMSM drive systems was carried out. The principles ... -
Stability analysis of a DC power grid for marine propulsion application
Hallqvist, Max Erik Oliver (Master thesis, 2016)DC-grids have no need to have frequency and phase control, and there is no problems regarding loses through reactive effect. Even so, there have been issues related to the security of DC-grids. One of the problems which ... -
Use of Energy Storage in a LVDC Distribution Network for Ships
Nebb, Ole Christian (Master thesis, 2012)This thesis has focused on the modeling of energy storage technologies such as Li-ion batteries and super capacitors, where they are connected to a DC bus with a bidirectional DC-DC converter. Two different energy storage ... -
Utvikling av hybrid strømforsyningsmodul for bruk i ubemannede fly
Bergsvåg, Tommy Daniel (Master thesis, 2016)Denne masteroppgaven forsøker å utvikle en lettvekt hybrid strømforsyning til et ubemannet flygende kjøretøy. Relevant teori om forbrenningsmotorer, permanent magnet maskiner og omformere er gjennomgått og en simuleringsmodell ... -
