Electronic Energy Systems

Highly Available and Efficient Power Conversion for the Future

Fraunhofer ISIT drives the energy transition by advancing power electronics for mission critical applications. We offer a comprehensive range of competencies – from developing high performances power devices and converters, to controlling advanced systems and hybrid grids.

The global DC-fication trend is transforming today's AC-dominated networks into hybrid LV/MV DC and AC/DC architectures, enabling higher efficiency, better use of existing infrastructure, and seamless integration of renewables and storage. Solid-state transformers (SSTs) are a key enabling technology for these hybrid grids, providing fast, controllable interfacess between AC and DC networks. 

As demand grows for reliable power in mobility, charging infrastructure, microgrids, data centers, and green hydrogen, we deliver innovative solutions: condition monitoring, digital twins, life extension algorithms, and fault tolerance.

Tailored Innovations for a Sustainable Energy Future

We help industries succeed with advanced hybrid grid technologies, multi-energy converters, and active reliability solutions. Hybrid LV/MV AC/DC networks with smart SSTs are the future - our expertise ensures high availability where downtime costs are highest.

Hybrid grids, combining sub-networks of different voltage levels and types (AC and DC) with solid state transformers (SST), are the future of the power distribution system - but mission-critical apps need ultra-reliable power converters. This can be supported by condition monitoring, digital twins, life extension control algorithms, and fault tolerance strategies.

Fraunhofer ISIT offers chip to system expertise, including converter development. This enables global optimisation of the entire system for high availability and ultra-high efficiency - at controlled costs.
