1. Pulse-width voltage modulation in the Python-based open-source simulator Motulator : A Realization of SVPWM, Harmonic analyzer and Over-modulation on Two and Three-level Inverters, and a Solution for Unbalanced Neutral Point Voltage on Three-level Inverters
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Controlling the dynamic outputs of electrical machines has always been an essential topic in aerospace, automotive and other industries. Electrical machine control consists of several components, each of which can be controlled in various ways. Whereas the dynamic responses are mostly simulated using MATLAB/SIMULINK, Prof. LÄS MER
2. Alternative traction system for road-rail vehicles
Master-uppsats, Lunds universitet/InnovationSammanfattning : Excavators have traditionally been diesel driven with hydraulic actuators, but with the ongoing electrification of vehicles, smaller electric excavators are getting more common. Larger electrical excavators are still in a prototyping or early production stage but can be expected to grow. LÄS MER
3. Implementering av variabelt varvtal i vattenkraftsaggregat : en förstudie
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikSammanfattning : Detta arbete har utrett möjligheten till att implementera variabelt varvtal hos bulbturbiner. Som utgångspunkt har anläggningar med ett Kaplanlöphjul och en växellåda analyserats där variabelt varvtal ska implementeras med en frekvensomriktare och ett löphjul med fasta skovelblad. LÄS MER
4. Design och framtagning avprototyp för reglering avhandtagsvärme på bensindriven motorsåg
M1-uppsats, Karlstads universitetSammanfattning : Husqvarna Group is a company specializing in forest and garden products. Among these products are chainsaws that incorporate functionality for handle heating. The current handle heating system is unregulated, and this report therefore addresses the development and construction of a prototype for controlling handle heating. LÄS MER
5. Process monitoring of turbine blades : Monitoring of blade tip clearance using eddy current sensors
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : This thesis has been a collaboration between the Royal Institute of Technology (KTH) and Siemens Energy which invest in the research facility at KTH. The objective was to investigate the use of eddy current sensors in real-time monitoring of turbine blades. LÄS MER
