ENABLE the Grid: Establishing a centre of excellence for resonance coupling in electricity supply systems
As the energy transition progresses, green and sustainable electricity supplies are facing considerable pressure to innovate. This stems, on the one hand, from demands for greater energy efficiency, the miniaturisation of circuits and significant cost reductions. On the other hand, due to the tight supply situation on the global market, strategic aspects relating to the availability of (sub-)technologies are also coming into focus. Overcoming these challenges is crucial to fully harnessing the benefits of resonant coupling technology and making future power supply systems more efficient and sustainable.

noLIMIT
Grid-oriented bidirectional charging with smart modules optimised for industrial manufacturing technology
The increasing electrification of the transport sector poses new challenges for the stable operation of the grid. For example, according to the Leopoldina National Academy of Sciences, charging behaviour in the low-voltage grid is one of three typical causes of future grid bottlenecks. However, electric vehicles can also be part of the solution: the electric vehicles planned for roll-out by 2030 offer very high storage potential, which can only be harnessed through bidirectional charging. To this end, the FTZ is developing novel power electronics for bidirectional high-power charging points as part of the ‘noLIMIT’ project. As a key element of sector coupling, the charging points are intended to contribute to efficient grid operation and, through innovative concepts, enable highly automated manufacturing in Germany.

MoFi-Flex
Modern, high-performance research infrastructure for innovative and flexible energy distribution systems using power electronic converters
The transient calorimetric power dissipation measurement facility planned as part of the ‘MoFi-Flex’ project is designed to determine power dissipation in power electronic components and systems with high precision. The measurement results will be used to characterise and thermally model active and passive components. The Chair is addressing the increasing demands placed on complex circuits and individual components, particularly in relation to the high-frequency operation of wide-bandgap semiconductors.
