  • PhD - High-Power Planar Magnetics for Future Automotive Converters

    Organization: Robert Bosch GmbH | Type: PhD position | Pay Range: - | Location: Robert-Bosch-Campus 1, 71272 Renningen, Germany | Recruiter/Contact: Julian Veitengruber | Deadline: 2024-12-31

    Description:
    Soft-magnetic components such as transformers and chokes are essential in automotive power-electronic converters such as chargers or DCDC-converters. They have a high impact on the overall device in terms of cost, size, and efficiency. To significantly improve these key components, Bosch research is looking for a PhD who can shape this exciting topic.

    In current converter systems like automotive onboard Chargers (OBC) the magnetics in the power-range of 11-22kW are based on discrete wire-wound magnetics. Those wire-wound magnetics are either labor-intensive or require product specific production lines. Development trends towards planar magnetics are seen in academia for quite some time and recently gain momentum due to new semiconductor device technologies enabling higher frequencies. However, the major limitation of this planar approach is given by the losses in the PCB-winding and the magnetic core besides integration aspects like cooling. This design trade-off will be one of the major parts of this PhD thesis.

    The main objective of the work will be the design of a 11kW charger with planar magnetics including the build-up and demonstration by an operational functional demonstrator. Beyond the general function, the main performance indicators will be a high efficiency and compact size. To reach that goal, new circuit topologies, magnetic design and integration approaches are required here, which will be the focus of the work.

    Qualifications:
    Education: Master degree with focus in Electrical Engineering or Physics with focus on Power Electronics and/or soft-magnetic components
    Experience and Knowledge: first lab experience in electronics and good command of Matlab/Simulink as well as first experience with FEM tools for electromagnetics
    Personality and Working Practice: autonomous, systematic, and proactive working style
    Languages: good in German and English or willingness to learn German

    The work takes place in the central research and advance development department of an industrial company. We ensure that 100% of your working time can be used for the PhD topics.
