The Power Electronics and Power Systems-Laboratory (PEPS-Lab) team researches power electronics for a safe, stable and sustainable energy supply and for electric vehicles with the following main topics:
Research for the next generation of smart and sustainable power electronics using SiC and GaN semiconductors
- Renewable energies - e.g. PV inverters (project: GaN-HighPower)
- Grid-forming battery inverters in interconnected and stand-alone grid operation to ensure system stability in current and future power grids (project: LEITNING)
- Rectifiers with system services for MW electrolysers (project: HyLeiT)
- for the connection of electrochemical energy sources - such as fuel cells, electrolysers, batteries - to DC grids (project: MarrakEsH)
- .E.g. fuel cells, electrolysers, batteries - to DC grids (project: MarrakEsH)
- Bidirectional charging technologies for electric vehicles (project: CombiPower)
Power grids
- Modelling of electrical energy supply systems on real-time computers (projects: F-HiL Reloaded, GRID-Cloud)
- Use of power hardware-in-the-loop systems - e.g. to map real grid connection conditions through real-time-capable power interfaces (projects: F-HiL Reloaded, PV4Life)
- Creation of digital twins of distribution grid structures with cloud data logging and cloud computing (project: GRID-Cloud)
- Development of novel examiner and test scenarios for islanding annexes/power converters (Project: F-HiL Reloaded)
- Development of novel communication protocols for test scenarios in P-HiL systems (Project: SIRFN JRA: Open SVP)
- Grid-forming converter control (Project: LEITNING)
