In the Faculty of Computer Science, Electrical Engineering and Mathematics at the Department of Power Electronics and Electrical Drives (LEA) a 

PhD Position as Scientific Coworker (f/m/d)

(salary level 13 TV-L)

in the DFG-funded research project “GaNius” is vacant. Project focus is the analysis and build-up of new low common mode three-phase PFC rectifier (applied e.g. in On-Board Chargers for EVs) utilizing the specific advantages of Gallium-Nitride (GaN) power semiconductors.

The employment covers 100 % of the regular working time and is initially limited to 3 years according to German legal regulations (Wissenschaftszeitvertragsgesetzes, “WissZeitVG”). This limitation corresponds to the granted project duration. An extension is presumed possible and desired. The opportunity of scientifically qualifying by a PhD thesis is given and explicitly supported.

Job description and tasks:

• Circuit simulations of new three-phase PFC topologies and DC-DC stages 
• Analytic analysis and dimensioning of various power topologies
• Experimental GaN-HEMT characterization, specifically of monolithic bidirectional devices, on existing test setups 
• Build-up and operation of three-phase PFC lab prototypes (about 11 kW) 
• Development and implementation of modulation- and control algorithms on DSP in C
• Verification, documentation and publication of results

Requirements of employment:

• Very good scientific university degree in Electrical Engineering, Control Engineering or comparable university studies (Master’s degree)
• Established knowledge in circuit simulation (e.g. Plecs, Simplorer, Simulink, etc.)
• Well-founded programming skills (C, Matlab/Simulink, VHDL if applicable)
• Good knowledge and practical experience in the dimensioning as well as in the prototype implementation of power electronic converters
• Appropriate experiences with DSP-based real-time control on embedded systems 
• Knowledge and experiences in analog circuits (e.g. gate drive- and sensing circuits), and ideally in PCB design 
• Self-reliant and team-oriented working attitude
• Good English in oral and written form

Applications from women are particularly welcome and, in case of equal qualifications and experience, will receive preferential treatment according to state law (LGG). Part-time employment is generally possible. Qualified disabled people (in the sense of the German social law SGB IX) are also encouraged to apply.

Applications with the usual documents (cover letter, CV, certificates in one PDF-file) and indicated by the reference number 6204 should be sent until February 29th 2024 to: sekretariat@lea.uni-paderborn.de.
