  1. 1. Numerical study of a jet impacting a heated object

    Kandidat-uppsats, Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)

    Författare :Moutaz Hammoud; [2023]
    Nyckelord :Numerical model; COMSOL Multiphysics; Heat transfer; Impinging jets.;

    Sammanfattning : Heat transfer brought about by impinging jets is common in several industrialapplications such as the cooling of heated objects. The purpose of this investigationis to create a numerical model of an impacting jet, then to use it in parametricresearch and in the cooling of an electronic device. LÄS MER

  3. 2. Convolutional-LSTM for IGBTs Prognostics and Age Monitoring : Designing a neural network for predicting aging precursors in power devices

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Matteo Santoro; [2023]
    Nyckelord :Neural Networks; Igbt; Prognostics; Age Monitoring; Neurala Nätverk; Igbt; Prognostik; Övervakning av Ålder;

    Sammanfattning : In recent years, extensive research efforts have been dedicated to the field of prognostics and age-related degradation, with major focus on higher complexity devices. However, relatively little attention has been given to power devices, such as Insulated Bipolar Gate Transistors (IGBTs), despite their critical role in high power electronic applications. LÄS MER

  4. 3. CURRENT OVERSAMPLING ANALYSIS FOR ADVANCED CONTROL OF ELECTRIC AC DRIVES

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Marco Giuliato; [2019]
    Nyckelord :;

    Sammanfattning : The main purpose of this thesis is to develop a sensorless control for a synchronous reluctance motor by using the slope measurement of the current ripple introduced by the Space Vector Modulation.The position estimation is performed at each Space Vector Pulse Width Modulation period and it relies on the estimation of current derivatives.

  5. 4. Maximum Inverter AC Current Prediction Based on Junction Temperature Calculation

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Shuyu Ou; [2019]
    Nyckelord :IGBT; Inverter; Junction temperature; Current Limiter; IGBT; Växelriktare; Övergångstemperatur; Strömbegränsare;

    Sammanfattning : Semiconductor devices are widely used in the automotive industry, and they are key components of the inverter and the converter in an electric vehicle. Thus, the concern of protecting the inverter and the converter from damaging operation has been raised. The junction temperature is one of the main considerations. LÄS MER

  7. 5. Development of EMT Simulation Model to Use RMS Control Model

    Master-uppsats, KTH/Skolan för elektro- och systemteknik (EES)

    Författare :Priya Kalikavunkal; [2016]
    Nyckelord :;

    Sammanfattning : Evolution is continuous and as a result, developments in semiconductors are endless. This led to the Voltage Source Converter (VSC) based High Voltage Direct Current (HVDC) converter termed as HVDC light. HVDC light is quite preferable because of its pros in the technology used as well as the application it is used for. LÄS MER
