Information about the division
The division of Electric Power Engineering is one of the four divisions within the department of Electrical Engineering at Chalmers University of Technology. The division has a strong commitment in research and education with its tasks to develop new knowledge, combine it with experiments, and pass it on to the students and to the society. In this way, the division has been contributing to securing the international competitive position of Sweden as a whole.

Our main research activities in the division are represented in five areas: (1) Power systems and grid-connected converters; (2) High voltage and insulation; (3) Renewable power and grid integration; (4) Electrical machines and drives; and (5) Electric vehicles and transport electrification.

Major responsibilities
- The main task for the PhD student will be study and design of integrated drive system for electric and hybrid vehicles. One of the task is to develop a SiC based converter which can be integrated on a motor. The converter and the motor share the housing and cooling ducts. The research will deal with power circuit design, driver design, cooling design, motor control, EMC and packaging. During the study period 2-3 prototypes at power level of 50-70 kW will be built and experimentally evaluated.

- The PhD student will also be involved work in an EU H2020 project with several academic and industrial partners. The project aims at developing next generation electric drives – highly efficient and compact integrated modular drivetrain and components - dedicated for mass produced electric and hybrid vehicles. The Chalmers part of the project is system design of the new concept drivetrain and research on extended functionalities of distributed drive. The system design will be conducted together with a vehicle manufacturer. The PhD student should be able to work independently and in team.

- The PhD student will be involved in topology study, component/device selection, simulation, system optimization, prototyping, and performance tests.

- The research will be conducted in such a way that theoretical study including simulation and optimization is combined with experimental verifications.

- The research results will be published as technical reports and scientific papers on peer review journals and international conferences.

- The PhD student position will normally include 15-20% departmental work, typically as lab assistant and exercise leader of different courses.

Position summary
A PhD student in Electric Power Engineering who will work with development of modular integrated drive system for electric and hybrid vehicles. Full-time temporary employment with all benefits of Swedish employments. The position is limited to a maximum of five years.

Qualifications
- To qualify as a PhD student, you must have a master's level degree corresponding to at least 240 higher education credits in Electrical Engineering.
- Good knowledge on power electronics, such as 3-ph converters, semiconductor devices, DC/DC converter, charging systems and their modelling methods, is required.
- Practical experience on experimental tests of electromagnetic devices, converters and their control is required.
- The design and simulation tools that will be used in the project include FEM tools such as Maxwell-2D/3D, and circuit simulation tools such as PSpice, LT-Spice, PLECS and Simulink. Experiences in some of these tools are required.
- Knowledge and experiences on electric drivetrains of electric or hybrid vehicles are meritorious.
- Applicants are expected to have an excellent knowledge of both written and spoken English. Since the university’s teaching activities are conducted in both Swedish and English, the knowledge of Swedish is an advantage.
- A lot of the work will be conducted together with other colleagues and collaboration partners. The spirit and personal skill for teamwork are highly appreciated.

Chalmers continuously strives to be an attractive employer. Equality and diversity are substantial foundations in all activities at Chalmers.
