  1. 1. Harmonisk strömsimulering i inverterbaserade värmepumpar

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Alexander Magnusson; [2023]
    Nyckelord :Current harmonics; inverter-driven compressor; black box simulation;

    Sammanfattning : An electrical distribution network supplies power to many households at a time. Each house has various types of electrical appliances which consume different levels of power depending on its function and the load it supplies. An ideal case would be when no appliances cause power disturbances, however, in reality, many electrical appliances (e.g. LÄS MER

  3. 2. Reglering av aerodynamiska element för lätta fordon

    Kandidat-uppsats, Högskolan i Halmstad/Akademin för informationsteknologi

    Författare :Jonathan Rendel; William Balte; [2022]
    Nyckelord :aktiv aerodynamik; reglerteknik; aktuator; reglersystem; nedåtkraft;

    Sammanfattning : Den här kandidatuppsatsen undersöker möjligheten att konstruera ett system som med hjälp av ett rörligt aerodynamiskt element reglerar den nedåtkraft ett fordon utsätts för vid olika störningar. För att manipulera det aerodynamiska elementet utvecklas en aktuator. LÄS MER

  4. 3. Model verification and common mode current analysis of grid connected three phase two level converters

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automation

    Författare :Simon Lindvall; Richard Haraldsson; [2021]
    Nyckelord :active filter; EMC; EMI; converter; common mode; differential mode; shunt active filter; parasitic elements; Technology and Engineering;

    Sammanfattning : In this Master’s thesis an in-depth model of a shunt active filter for high frequency analysis is constructed. The purpose is to enable analysis of higher frequency behavior reaching 1MHz. Using the high frequency model, common mode currents can be simulated. LÄS MER

  5. 4. Estimation of Stability Margins for the Closed-Loop Air Charge Control of an Internal Combustion Engine Using Sinusoidal Disturbances

    Master-uppsats, Linköpings universitet/Fordonssystem

    Författare :Victor Sundelin; Filip Jussila; [2021]
    Nyckelord :Estimation; Stability Margins; Closed-Loop; Air Charge Control; Internal Combustion Engine; ICE; Sinusoidal Disturbances;

    Sammanfattning : The vehicle industry have for many years improved the design of car motors and iterated the control systems associated with it. The systems have become very complex and hard to understand because of this work process. LÄS MER

  7. 5. Ventricular fibrillation detection with Neural Networks

    Master-uppsats, KTH/Skolan för teknik och hälsa (STH)

    Författare :Carl Klinglöf; [2012]
    Nyckelord :ventricular fibrillation neural network;

    Sammanfattning : A solution to distinguish ventricular fibrillation and ventricular flutter from other arrhythmias and from disturbances caused by body motion or muscle activity with the use of a neural network has been investigated. Ventricular fibrillation and ventricular flutter occurs when the cardiac muscle cells are not triggered by the cardiac conduction system, but rather by ectopic foci preventing a synchronized contraction of the cardiac muscle cells and therefore inhibiting the hearts capability to properly pump blood.
