Wire or ribbon connections made of aluminum are usually used to transmit electrical power in control units and power electronics modules. Since the connection points of the wires and ribbons are usually located on substrates made of different materials and the components are frequently exposed to external temperature differences, cracks can form in the material during operation and lead to complete failure of the component, which cannot be remedied by simple design modifications.

The field of photovoltaics has been subject to enormous price pressure for many years, as falling feed-in tariffs worldwide make low component prices necessary to be able to manufacture and operate a PV system economically. At the same time, the demands on the functional diversity of the devices continue to increase (e.g. universal use in PV and battery applications, grid feeding, self-consumption and island operation, provision of grid services).

In the HyLeiT joint project, research is being conducted into a new generation of electrolysis converters and electrical system technology for the energy supply of hydrogen electrolysis. The aim is to halve the system costs of electrical engineering from the grid connection point to the DC connection at the electrolyzer, taking into account associated operating costs and effects on H2 generation costs.

The potentials and effects of digitalisation today encompass all areas of human and social activity. Universities are therefore responsible for enabling their students to develop competences that not only include the competent use of digital technologies, but also the ability to assess the potential and effects of digitisation in society and the world of work, to actively and reflexively shape digitisation processes and to keep pace with the rapid dynamics of change. In 2019/2020, the state of North Rhine-Westphalia developed the Curriculum 4.0.nrw funding line, which is intended to support the Hochschule Bonn-Rhein-Sieg in exploiting the opportunities of digital teaching, among other things. In the Department of Electrical Engineering, Mechanical Engineering and Technical Journalism, this funding line will be used to further develop the Master's programme in Sustainable Engineering Sciences, which addresses the funding line's thematic areas such as technical innovation and digitalisation.

In the LEITNING project, a novel battery inverter with high mass power density is being researched and field tested to provide a highly-available and modular AC grid and grid-supporting functions using advanced circuit topologies based on innovative SiC MOSFET power modules, magnetic devices and control strategies.
