Thesis Worker at Volvo Cars
Welcome to explore the world of Volvo Cars by writing your thesis with us! As a thesis worker in our organization you are supported by a supervisor who follows you during your project. Through your thesis work you will be able to contribute to our company purpose – providing freedom to move in a safe, sustainable and personal way – from day one!
As Volvo Cars continues to lead the transition to sustainable mobility, the integration of advanced charging technologies becomes increasingly critical. One such innovation is the DC Boost function, which utilizes the electric vehicle’s inverter and E-machine as a bidirectional DC-DC converter. This enables stepping up a 400V input to charge an 800V high-voltage battery—crucial for compatibility with legacy charging infrastructure. Conversely, it can also step down the voltage for Vehicle-to-Everything (V2X) applications.
The objective of this thesis is to optimize the current DC Booster topology by thoroughly analyzing the electrical and electromagnetic behavior of the motor drive system, comprising the inverter and E-machine. While conventional booster topologies typically utilize all the phases for the complete power/ state of charge range, this work will investigate the feasibility and performance implications of engaging/ disengaging the three phases to achieve enhanced system optimization and performance efficiency. The investigation will be conducted in two stages. In the first stage, the candidate will concentrate on the modelling and control of a three-phase DC booster. Upon successful completion and satisfactory progress in stage one, the candidate will proceed to the testing phase, where they will validate their findings using a physical test setup.
The ideal candidate should possess a solid understanding of electric machines, power electronics, control systems, and electric propulsion technologies. They should be capable of simulating electric drive systems while accounting for electrical, electronic, and electromagnetic interactions.
Key responsibilities include, but are not limited to:
Stage 1- Simulation
Stage 2- Testing
General
We are looking for you within the Master of Science program with Electrical, Power Electronics/ Control Systems and/or Machines. The ideal candidate should possess a solid understanding of control systems, electric machines, power electronics, and electric propulsion technologies. You should be interested in solving challenges individually and in collaboration with a positive mindset.
You are expected to perform the thesis work on site.
