  1. 21. Modeling of Resonances in a Converter Module including Characterization of IGBT Parasitics

    University essay from KTH/Elektrisk energiomvandling

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

    Abstract : 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. READ MORE

  3. 22. Modeling of IGBT Modules with Parasitics Elements Evaluation

    University essay from Sektionen för Informationsvetenskap, Data– och Elektroteknik (IDE)

    Author : Zahra Norouzian; [2013]
    Keywords : IGBT; Module; Parasitics;

    Abstract : The goal of this report is the development of a PSpice based modeling platform for the evaluation of power IGBT modules to be used in HVDC and FACTS applications. The use of simulation tools is of great value in the process of developing new power electronic devices and new converter topologies. READ MORE

  4. 23. Digitally Controlled Current Source Amplifiers for Power Converter Gate Drive Units

    University essay from KTH/Elektrisk energiomvandling

    Author : Mathias Scheele; [2013]
    Keywords : ;

    Abstract : Within this project, performance differences of 3.3 kV / 1500 A IGBT modules of the same type, but of different production batches are being investigated while the modules are being driven by the gate drive units of Bombardier Transportation. The results will be compared to measurements of a reference module. READ MORE

  5. 24. DC to AC inverter card with IGBTs : Construction and performance

    University essay from Uppsala universitet/Institutionen för teknikvetenskaper

    Author : Johannes Eriksson; [2012]
    Keywords : AC to DC; IGBT; Inverter;

    Abstract : This paper presents the construction and evaluation of a DC to AC inverter with IGBT:s and the basic PCD-layout for the single IGBT drivers. The main work consisted of constructing a PCB-card for controlling a number of IGBT:s, simulate its properties and test driving it. READ MORE

  6. 25. IGCT Transient Analysis and Clamp Circuit Design for VSC valves

    University essay from KTH/Elektrisk energiomvandling

    Author : Sanchit Singh; [2012]
    Keywords : ;

    Abstract : In today’s high power VSCs (Voltage Source Converters), IGBTs (Insulated Gate Bipolar Transistors) are the dominant semiconductors. These converters are in general modular multilevel based and contain several building blocks that are series connected. Each of these building blocks in turn consist of several series connected IGBT valves. READ MORE
