Job Description

Power electronic systems usually consist of many complex sub-modules. One central element is the auxiliary power supply in the power range of approx. 50-500W. This sub-module has to reliably provide the supply voltage, which is usually at high-voltage potential, for the internal low-voltage consumers. Highly automated applications such as autonomous driving place the highest demands on the availability, reliability and operational lifetime of the power supply. The following PhD aims to significantly optimize these isolated DCDC converters in terms of power density and size without making concessions in terms of efficiency, costs, reliability and functional safety. New revolutionary and innovative circuit and integration approaches are required here, which will be the focus of the work.

  • Within our team you will generate ideas and select suitable isolated DCDC converter concepts for highest power densities considering the feasibility in automotive applications.
  • You will evaluate converter concepts regarding the relevant qualitative and quantifiable criteria (costs, installation space, weight, scalability, isolation requirements and functional safety).
  • Analysis and derivation of relevant requirements for Hi-Rel applications (High Reliability) will be also one of your tasks.
  • You will model and optimize suitable converter concepts and the galvanic isolation stage in MATLAB Simulink / PLECS as well as FEM-based tools (magnetic components).
  • Furthermore, you will develop integration concepts for relevant application areas/products regarding packaging, insulation barriers, heat dissipation, etc.
  • Your responsibility includes the design, build-up and measurement of the most promising converter concept as a functional prototype.
  • Regular presentations, discussions and documentations of the results as well as the publication of the research results at international conferences and in leading journals are also part of your tasks within the framework of the PhD.

The work takes place in the corporate research and development center of Bosch. We ensure that your full working time can be used for the PhD.

Qualifications

  • Education: excellent Master degree in electrical engineering with a focus on power electronics
  • Personality and Working Practice: creative, convincing, structured as well as conscientious team player
  • Experience and Knowledge: knowledge in MATLAB / Simulink / PLECS as well as in the design and commissioning of electronic circuits, knowledge in 3D simulation tools (CST/Ansys) for thermal and magnetic simulations is an advantage, good understanding of the physics of DCDC converters, semiconductor and inductive components
  • Enthusiasm: passionate about research
