The PV4Life project is investigating the service life of photovoltaic power converters with a view to developing a digital twin of the power converter incorporating service life parameters. This model of the power converter is to be incorporated into the development of an artificial intelligence (AI)-supported operating strategy. This strategy optimises the utilisation and service life of PV power converter systems by adjusting the operating parameters as the system ages.

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.

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.
