Masterthesis (m/w/d): Investigation of a MMC topology as a storage converter for a high voltage battery up to 10kV

AEG Power Solutions offers a wide range of future-oriented career opportunities for people with the appropriate skills and the drive to make the difference in an agile, customer-focused, and global organization. AEG Power Solutions is looking for team players who want to continue to efficiently secure power supply to all types of infrastructures, contribute to renewable energy integration with its energy storage solutions and hydrogen production solution.

Put the skills you have acquired during your studies into practice and complete your final thesis with us.

Large battery storage systems are already supporting the energy transition by temporarily storing surplus energy from wind and sun, trending towards larger battery storage systems. In order to minimize losses, the KV-Bat-Syst research project is investigating a high-voltage battery that significantly reduces the power required for the same amount of stored energy. The topology of a modular multilevel converter (MMC) is being investigated, which is capable of blocking even very high voltages and thus makes the operation of a high-voltage battery possible in the first place.

Tasks and goals

• Literature research, overview of the state of the art
• Investigate possible components for an MMC circuit
• Designing and investigating a MMC stack
• Simulation of a MMC stack and calculation of overvoltage & losses
• Investigation of snubber circuit and control if necessary
• Goal: Concept and simulation of MMC topology as storage power converter for a high voltage battery up to 10kV

requirements:

• Attendance of the lectures Power Electronics (or comparable course) 

• Experience with simulation tools like Matlab or Octave

What we offer:

• An innovative, global company that combines tradition with modernity

• A modern team 

• We deal with the future technologies of tomorrow, with your work you can help shape them in a groundbreaking way
