    Sammanfattning : The falling cost of batteries, along with an increasing need to cut emissions, has spurred significant interest in the electrification of vehicles. In addition, as semiconductor devices have evolved, the research for electric vehicles with higher battery voltage has increased. LÄS MER

  3. 2. State-of-the-art DC Current Interruption Concept using SiCMOSFETs

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

    Författare :Georgios Papadopoulos; [2019]
    Nyckelord :;

    Sammanfattning : The transportation is in transition to the electrification era where the main source of energy for thevehicles is supplied by high energy propulsion batteries with voltages above 400 V. Currently the majority of the batteries are lithium-ion batteries and it is crucial to protect them from shortcircuits in order to ensure the safe operation in case of a vehicle crash or misuse of the vehicle.

  4. 3. Sensorless algorithm for synchronous machines using current oversampling and PWM harmonics

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

    Författare :Giorgio Gullone; [2018]
    Nyckelord :;

    Sammanfattning : Sensorless-controlled drives represent a solution drawing an increasinglyimportant attention for the benefits they entail. At the cost ofa slightly lower dynamics compared with the traditional drives, theyinvolve a reduction of the system costs and complexity and improvednoise immunity and reliability. LÄS MER

  5. 4. Control, Design, and Implementation of Quasi Z-source Cascaded H-Bridge Inverter

    M1-uppsats, Linköpings universitet/Elektroniska Kretsar och System

    Författare :Fares Al-Egli; Hassan Mohamed Moumin; [2018]
    Nyckelord :Quasi Z-Source Inverter; QZSI; Multi-Level Inverter; Single-Phase; Cascaded H-Bridge; PS-PWM;

    Sammanfattning : This report is about control, design and implementation of a low voltage-fed quasi Z-source three-level inverter. The topology has been interesting for photovoltaic-systems due to its ability to boost the incoming voltage without needing an extra switching control. LÄS MER
