TU Darmstadt

The Institute for Power Electronics and Control of Drives at the TU Darmstadt was founded in 1963, making it one of the first institutes for power electronics worldwide. The institute has pioneered methods, e.g. for the field-oriented control of asynchronous machines and the operation of HVDC systems.
 
Today's research can be divided into two main topics:


Interaction of power electronic systems and the power grid
The focus here is on active harmonic damping, optimization of line filters, behavior in case of unbalanced load, avoidance of undesired balancing processes via the mains and oscillations (both fundamental frequency and higher frequency) between power electronic systems, off-grid operation including black start capability.


Energy-efficient drives
Reluctance motors can be used as an alternative to the permanent-magnet-excited synchronous machine and asynchronous machine. However, reluctance motors can be controlled and positioned only with great effort over the entire speed range, especially when no angle encoder is available for cost reasons.
