Our research topics include:
- Mathematical modeling of electric drives and power converters, including the impact of system nonlinearities.
- Design of modern power converter topologies (i.e., printed circuit boards) based on promising components such as GaN and SiC.
- Development of control strategies for converters and drives on digital signal controllers, with an emphasis on increasing the efficiency and effectiveness of controlled systems and enhancing power density. We mainly focus on electric drives for road traction and chargers for electric vehicles.
- Research and development of new modulation strategies for controlling AC drives.
Our designed control algorithms can, for example, ensure that an electric drive consumes less energy from the source in a given operating point, i.e., at certain speeds and torque on the shaft, or maximize its torque utilization across the entire operating range. Through modulation algorithms for converters, we can reduce losses in the converter and drive and maximize the use of the power source, which is crucial for battery-powered electric vehicles. Our mathematical models can compensate for parameter changes and the influence of nonlinearities, thereby enhancing real-time control algorithms.
