PhD Student Insulation Materials Electric Drives

The topic involves the development and improvement of electrical insulation systems and materials, as well as corresponding lifetime modeling. These materials are intended for use in electric drive systems in battery electric vehicles (BEVs). The challenge is to ensure the insulation capability of the insulation system, especially under high voltage rise gradients and elevated operating temperatures in the electrical components 'electric machine' and 'power electronics' for controlling the machine. The topic not only includes the specific application but also the determination of the failure mechanisms of the materials in use and the physical-based modeling of the degradation of the material and the system. Based on this, service lifetimes are to be estimated, which can be used and calibrated for determining the product lifetime over mission profiles. Furthermore, in addition to the materials, the property descriptions, qualification, and testing and analysis techniques are to be researched and developed.
