1. 1. 3D High Frequency Modelling of Motor Converter and Cables in Propulsion Systems

   Uppsats för yrkesexamina på avancerad nivå, KTH/Elektroteknisk teori och konstruktion

   Författare :NJIOMOUO STEPHANE YANNICK; [2014]
   Nyckelord :;

   Sammanfattning : The use of the power converters in railway traction systems introduces high frequency electromagnetic interference (EMI) in the propulsion system, which causes electromagnetic compatibility (EMC) problems. These high frequency phenomena come from fast variations of current and voltage during the switching operations in the power converter. LÄS MER

3. 2. Modeling of Resonances in a Converter Module including Characterization of IGBT Parasitics

   Uppsats för yrkesexamina på avancerad nivå, KTH/Elektrisk energiomvandling

   Författare :Ensa Sinyan; [2013]
   Nyckelord :IGBT bus-bars; CST; high frequency modeling; EMC; EMI; parasitic resonances;

   Sammanfattning : Fast switching operations in IGBTs generate electromagnetic field disturbances, which might cause EMI and functionality issues. For higher frequency characterization, the parasitic inductances and capacitances have to be considered. LÄS MER
