  4. 2. Physical modeling of on-state losses in bipolar Si and SiC power devices

    Author : Olof Tornblad; KTH; []
    Keywords : ;

    Abstract : Power losses affect both the installation- and long-term cost of power electronic systems. The installation cost is related to the fatt that power losses in silicon power devices generate heat and make installation of heat sinks and water cooling necessary. If self-heating effects are strong, lotal overheating can eventually lead to device failure. READ MORE
