Power Converter Systems

In many parts of the world, the electricity production costs of renewable energies and in particular photovoltaics (PV) are now clearly competitive. Energy storage systems are also proving to be very cost effective, which is why an ever broader use of sustainable energies is to be expected. Suitable power electronic systems are central components, both for processing electrical energy and for system integration into an increasingly complex and intelligent energy system. Thanks to innovative hardware designs, optimized cooling systems and specific control technology, we can develop such converter systems in almost all performance classes. These can be upgraded for grid-connected, off-grid and hybrid applications.

In the wake of the energy revolution, the decarbonization of the transport sector is increasingly being realized through the electrification of the powertrain. In order to make the electrical energy available to the electric drive in an application-specific and correct form, a large number of power electronic converters are required. For this purpose we develop application-specific solutions such as highly efficient bidirectional charging systems. These enable the vehicles to be charged efficiently and the stored energy to be fed back in the power grid if needed. The integration of grid-supporting and grid-building functions is also part of our research focus. In addition, we develop highly compact on-board converters which, for example, efficiently and intelligently couple the traction battery to the actuators.
