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

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Rishi Balasubramanian Saraswathy; [2022]
    Keywords : 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;

    Abstract : 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. READ MORE

    Abstract : The automotive industry is undertaking major technological steps in an effort to reduce emissions and fight climate change. To reduce the reliability on fossil fuels a lot of research is invested into electric motors (EM) and their applications. READ MORE

  4. 3. State of the art within life cycle assessments of lithium-ion batteries : an investigative study of key differences in previous studies and future needs of research

    University essay from SLU/Dept. of Energy and Technology

    Author : Lollo Liu; [2020]
    Keywords : life cycle assessment methods; lithium-ion batteries; electric vehicle; environmental impact;

    Abstract : The use of electric vehicles has seen a rapid growth in the past decade as it is expected to have an important role in mitigating greenhouse gas emissions from the transport sector. The increased demand for electric vehicles has in turn amplified the demand for traction batteries, especially lithium-ion batteries. READ MORE

  5. 4. Visualization and simulation of idle truck energy usage : Prediction of battery discharge in a Volvo truck cab

    University essay from

    Author : Simon Elvmarker; [2018]
    Keywords : energy usage; battery management; climate system; simulations;

    Abstract : Volvo Group Trucks Technology has found a need for a new way to present the battery status and electricity consumption of their on-board batteries in combustion engine trucks. Many battery related issues the drivers are facing could be prevented if a tool was developed that could assist with energy planning in an intuitive way. READ MORE

  6. 5. Willingness to Pay to Avoid the Cost of Intermittent Water Supply

    University essay from Göteborgs universitet/Graduate School

    Author : Nining Widiyati; [2011-07-18]
    Keywords : contingent valuation; intermittent supply; private sector; willingness to pay;

    Abstract : This study summarizes the results of a contingent valuation survey of 200 households in Bandung, Indonesia for 24-hour water supply. The existing piped water supply in the city is intermittent and unreliable giving rise to additional cost to piped water users as well as inducing excessive use of ground water leading to the depletion of water table and land subsidence.
