Control of Six-Phase Machines
Hoem, Øivind Michael Molnes (Master thesis, 2010)The purpose of the work presented in this report was to continue the study of a six phase dual winding IPMSM with split dc-link conducted in [1]. The setup has been proposed as a means to improve the power ratings of ... -
Fixed Speed Electric Motor Drives for LNG Refrigeration Compressors.: Back-to-Back Starting Methods and Grid Consequences.
Breistein, Hallvard (Master thesis, 2009)Experimental studies as well as simulations have been performed on the Back-to-Back starting schemes low frequency-, partial frequency-, and soft -start-up. A Back-to-Back configuration of two synchronous machines has been ... -
Implementation of Permanent Magnet Motors in Electric Vehicles
Elvestad, Eirik (Master thesis, 2008)This thesis has studied permanent magnet motors in electric vehicles (EVs) under the assumption that they are tractable due to a low weight and high compactness. The implementation has been investigated through a case ... -
Modeling, simulation and implementation of Multi-phase Induction Motor Drives.
Thopate, Sachin (Master thesis, 2011)The results obtained in the simulations and the actual results that are observed on the SPIM drive for the DSFCC strategy are in agreement. The operations of the control strategies during the extreme conditions were tested ... -
Modelling and Control of Six-Phase Induction Motor Drive
Araya, Nebrom Berihu (Master thesis, 2012)Multiphase machines are of interest to be applied in electric ship propulsion, where increased power ratings, reliability of operation, redundancy and efficiency are required. The study of modelling and control of multiphase ... -
Wave Energy Conversion: Simulation Verification and Linearization of Direct Drive Wave Energy Converter with Variable DC-link Voltage Control
Ditlefsen, Arne Marius (Master thesis, 2009)Lowering the cost of wave energy conversion is an essential task for it to succeed as a future energy resource. In this work a converter, assumed cheaper than the regular back to back converter setting, have been investigated ...
