1. Design and Assessment of HVDC Off-shore Wind Turbine Generator
Abstract : In this work, design and assessment of a 5 MW wind energy generator with a gearbox is performed to find an energy-efficient generator for HVDC offshore wind turbines, studying aninterior permanent magnet synchronous generator (IPMSG) as well as a permanent magnetassisted synchronous reluctance generator (PMa-SynRG). Quantities such as torque density,torque ripple, losses and amount of magnet material are studied. READ MORE

2. Efficiency Analysis of Drive-train for an Electrified Vehicle
Abstract : In this PhD thesis, various solutions to improve the energy efficiency in the electrical drive-train of an electrified vehicle such as modifications of the propulsioninverter or control of the electric machine, are proposed and their benefits arequantified from an energy efficiency point of view. The efficiency analysis isbased on modeling of a power electronics inverter, an electric machine and a battery in various drive cycles for an electrified vehicle. READ MORE
