  1. 1. Analysis and Performance Evaluation of a Three-phase Three-level Sparse Neutral Point Clamped Converter for Industrial Variable Speed Drives

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

    Författare :Pengpeng Sun; [2022]
    Nyckelord :Sparse Neutral Point Clamped Converter; Industrial Variable Speed Drives; Silicon IGBT; Calorimetric Measurement; Reverse Recovery Energy; Sparse Neutral Point Clamped Converter; Industriella Varvtalsstyrda Motordrifter; Silicon IGBT; Kalorimetrisk Mätning; Energi för Återhämtningsprocess;

    Sammanfattning : This thesis project focuses on the simulation, design, hardware realization, and performance evaluation of a Three-phase Three-level (3-L) Sparse Neutral Point Clamped Converter (SNPCC) for Industrial Variable Speed Drives (VSDs). The basic operating principle of the SNPCC is briefly described based on switching functions. LÄS MER

  3. 2. Numerical Simulation of 3.3 kV–10 kV Silicon Carbide Super Junction-MOSFETs for High Power Electronic Applications

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

    Författare :Rishi Balasubramanian Saraswathy; [2022]
    Nyckelord :Super–Junction; DMOSFET; 4H-SiC; Silicon Carbide; Wide bandgap; 6.5 kV; 10 kV; On-state resistance; Breakdown voltage; Super–Junction; DMOSFET; 4H-SiC; kiselkarbid; bredbandgap; 6.5 kV; 10 kV; framspänningsfall; spärrspänning;

    Sammanfattning : The thesis focuses on designing and characterizing SiC 3.3 kV Diffused Metal-Oxide Semiconductor Field-Effect Transistor (DMOSFET)s with a Ron that is significantly lower than that of current commercial devices. The On-state resistance and breakdown voltage are then adjusted by adding a Super-Junction structure. LÄS MER

  4. 3. Reliability Study of SiC-Based Power Electronic Devices in DC-DC Converter Used in Heavy-Duty Electric and Hybrid Vehicles

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

    Författare :Sanaz Namayantavana; [2017]
    Nyckelord :;

    Sammanfattning : A DC-DC converter is used in electrified and hybrid vehicles to supply powerto the low voltage (ex. 24V) system including headlights, horn, air conditioningsystem, wipers, radio, etc. The converter is fed from a high voltage (ex. 650V)battery, which is available in electric/hybrid vehicles, and transfers a relativelyhigh power.
