  1. 16. Modeling of HVDC IGBT in Pspice : Serving an ultimate goal for converter station EMC studies

    University essay from KTH/Elektroteknisk teori och konstruktion

    Author : Jin Yang; [2015]
    Keywords : StakPakTM IGBT module; IGBT behavioral model; Single pulse test circuit; Generation 4;

    Abstract : An IGBT/diode model with more accurate characteristics than simple switchis required to serve for EMC issues from converter valve. The purpose of thismaster thesis is to develop an IGBT and diode model to achieve both accuratetransient behavior and fast simulation time during single pulse switchingtest circuit for the 4:5 kV and 2:0 kA StakPakTM IGBT module.

  3. 17. On-line estimation of junction temperatures in power modules

    University essay from Lunds universitet/Industriell elektroteknik och automation

    Author : Josefin Lund; [2014]
    Keywords : junction temperature estimation; foster circuit; thermal Ohms law; thermal resistance; thermal capacitance; time constant; Technology and Engineering;

    Abstract : It is critical for the durability of power modules to maintain low enough temperature in their components (IGBTs and diodes). The goal of this project was to examine methods to estimate the junction temperature of components in an IGBT module in real-time. READ MORE

  4. 18. 3D High Frequency Modelling of Motor Converter and Cables in Propulsion Systems

    University essay from KTH/Elektroteknisk teori och konstruktion

    Author : NJIOMOUO STEPHANE YANNICK; [2014]
    Keywords : ;

    Abstract : 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. READ MORE

  5. 19. Multi-level converter topologies for low voltage drives

    University essay from Lunds universitet/Högskoleingenjörsutbildning i datateknik

    Author : Max Fjelner Collins; [2013]
    Keywords : multi-level; inverter; converter; low voltage; igbt; loss-estimation; Technology and Engineering;

    Abstract : Inverters synthesizing output voltages consisting of two levels, commonly known as two-level inverters, have dominated the global market for a long time. Today, further emphasis is being put on inverter efficiency and power quality. READ MORE

  6. 20. Modeling of an IGBT and a Gate Unit

    University essay from KTH/Elektrisk energiomvandling

    Author : Henrik Hollander; [2013]
    Keywords : IGBT model; Behavioral model; Single Pulse Test Circuit; Gate Unit model;

    Abstract : The purpose of this master thesis was to create a model of an IGBT in a single pulse test circuit and connect this model to a model of a Gate Unit. The IGBT model and the single pulse test circuit were both implemented in MATLAB and the Gate Unit was implemented in Simulink. READ MORE
