Master Thesis: System Analysis of Wide Bandgap

vor 5 Monaten

Villach, 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 **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.**

**Further Information**
Type of employment: Temporary / Full-time (flexible working hours from Monday to Friday between 6 a.m. and 7 p.m.)

Duration: min. 8 months

You successfully meet the requirements, if you are a motivated and committed student from the field of
**Electrical Engineering, Electronics, Robotics, Mechatronics **or similar. You are best equipped for this task if your profile matches the following criteria:

- Completed all of your exams
- Knowledge and experience in **power electronics **(SPICE), **system simulation **(Simulink, FEM) and **programming **(MATLAB, C/C++)
- Knowledge and experience in **practical lab work**:

- Communicate well with our international team in English and German
- Good **communication **and **organizational **skills
- Motivation letter
- CV
- Certificate of matriculation at a university
- Latest Transcript of records (not older than 6 months)
- Highest completed educational certificate (Matura certificate for Bachelor students, Bachelor certificate for Master students)
- Reference letter (optional)

More than 5.000 people work at five different sites in Austria.

**Driving decarbonization and digitalization. Together.**

**- Power & Sensor Systems (PSS) drives leading-edge power management, sensing and data transfer capabilities -**

Infineon PSS semiconductors play a vital role in enabling intelligent power management, smart sensitivity as well as fast and reliable data processing in an increasingly digitalized world. Our leading-edge power devices make chargers, adapters, power tools and lighting systems smarter, smaller, lighter and more energy-efficient. Our trusted sensors increase the context sensitivity of “things” and systems such as HMI, and our RF chips power fast and reliable data communication.
