Power Converters

In the topic "Power Converters" we research, develop, evaluate and test new types of power electronic components, circuits and control algorithms as well as innovative assembly, connection and cooling concepts. Our aim is to set new benchmarks and bring progressive ideas to market maturity together with our partners from industry and research.

Within our research projects, we are continuously working on increasing volumetric and gravimetric power densities and optimizing losses and costs in power electronic systems. In the context of the energy, transportation and heat transition, aspects for increasing the reliability and sustainability of power converters are increasingly coming to the fore due to the limited resources available.

We specialize in the development of customer-specific solutions for electromobility and charging infrastructure applications as well as photovoltaic and storage systems up to pre-series production. Together with OEMs, their suppliers and manufacturers of components and subsystems, we realize innovative and individual solutions for power electronic systems.

In addition to our broad expertise, we have a unique and high-tech laboratory infrastructure at Fraunhofer ISE. This basis enables us to establish the comprehensive advantages of the next generation of our innovative power converters in other applications such as industrial power supplies or aerospace applications.
