Master Thesis: System Analysis of Wide Bandgap

vor 2 Wochen


Villach, Kärnten, Österreich Infineon Technologies Vollzeit
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
    stateoftheart 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.
