  1. 1. Parametrization of a Lithium-ion battery

    University essay from KTH/Kemiteknik

    Author : Elsa Arksand; [2021]
    Keywords : Parametrization; LiFePO4; Single particle model; Li-ion battery; Pseudo-OCV; Parametrisering; LiFePO4; Singlepartikelmodell; Litiumjonbatteri; Pseudo-OCV;

    Abstract : Batterimodeller används för att representera batterier. För ändamål som batterihanteringssystem används idag främst empiriska modeller som representerar ett batteri med en motsvarande kretsmodell. Några nackdelar för dessa modeller ligger i dess oförmåga att simulera interna tillstånd och en tidskrävande parametriseringsprocess. READ MORE

  3. 2. Investigating Optical-Field-Induced Currents in GaN using Ultrafast Lasers

  6. 5. 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
