Multi-Energy Converters

As the world becomes increasingly focused on electrification and renewable power, Multi-Energy Converters are becoming essential components of modern power systems. This technology offered by the EES group enables the efficient interconnection of multiple energy sources, taking advantage of technological advancements to achieve high integration.  

As we integrate multiple sources of energy, it is essential to focus on designing and developing power electronics systems at different voltage and power levels. This helps address the new challenges posed by interconnecting renewable and energy storage systems alongside power converters.

  • Long standing expertise from Prof. Liserre’s teams at the Chair of power Electronics and Fraunhofer ISIT in the development, control, and testing of Power Converters.
  • Cooperation with academics specialised in battery and super-capacitor development.
  • Laboratory dedicated to the development and characterization of Power Electronics-based Energy Conversion Systems.

The challenge includes the need for a high power density to meet size constraints, bidirectional energy flow between multiple energy sources at different voltage and power levels, controllability of the power converter, galvanic isolation required for safety aspects, and availability to ensure continuous operation of the system even under fault scenarios.
