1. 1. Experimental Comparison of Losses in a Grid-connected and M2C-fed 11kW Induction Motor

   Uppsats för yrkesexamina på avancerad nivå, KTH/Elektrisk energiomvandling

   Författare :GUSTAV MÖRÉE; [2015]
   Nyckelord :power losses; electric machines; AC-machines; induction machines; harmonic content; iron losses; modular multilevel converter M2C ; effektförluster; elektriska maskiner; AC-maskiner; asynkronmaskiner; övertonsinnehåll; järnförluster; modulär multinivå omvandlare M2C ;

   Sammanfattning : This thesis analyzes the power losses in induction machines and how the losses depend on the harmonic content of the applied voltages. Two cases are compared, one case where a machine is fed with a sinusoidial voltage and one case with a modular multilevel converter (M2C). LÄS MER

3. 2. Comparison of Different Methods to Measure Submodule Capacitor Voltages of Modular Multilevel Converters for HVDC Applications

   Sammanfattning : The Modular Multilevel Converter (M2C) is proven to be a key converter technology which is suitable for various high-voltage high-power applications. It offers several advantages over the conventional Voltage Source Converters(VSC) and multilevel converters.This Thesis deals with the measurement system for an M2C. LÄS MER

4. 3. ANALYSIS, IMPLEMENTATION AND EXPERIMENTAL EVALUATION OF A PHASE SHIFTED PWM CONTROL SYSTEM FOR A MODULAR MULTILEVEL CONVERTER

   L3-uppsats, KTH/Elektrisk energiomvandling

   Författare :Juan Colmenares; [2011]
   Nyckelord :;

   Sammanfattning : Nowadays, it is problematic to connect only one power semiconductor switch directly to the grid due to the high voltage range. In order to solve this difficulty, a new type of power converter has been introduced as a solution in high power applications. LÄS MER
