Job description

During your thesis project, we expect you to become a growing expert for motor drive systems for the fast-growing market of autonomous robotics. The overall goal of this thesis is the investigation of system losses of a motor drive system consisting of a wide bandgap inverter stage as well as a motor and control unit. This means you will need to acquire some special knowledge and perform dedicated tasks:

• Knowledge gathering about state-of-the-art motor loss and inverter loss models as well as control strategies for motor drives
• Development of a loss model based on co-simulation techniques, i.e. coupling Finite Element Method (FEM) simulations with system simulations
• Implementation of the loss model into an existing simulation framework
• Validation of the simulation results with real-world experiments
• Document your results by writing and submitting your Master Thesis

Special focus will be on the analysis of harmonic losses on a low-inductance motor, which is excited by high-frequency pulse width modulation techniques. The loss model should then be used as an adaptation to an already existing motor and inverter model and validated by real-world measurements in a lab environment.

This thesis has to be written in cooperation with an university.
