Novel transistors for highly efficient rectifiers and inverters

The integration of renewable energies requires the extensive use of storage and generation devices such as batteries and fuel cells. These devices are connected to the energy grid with the help of power electronic components. Converters play a central role in this process, enabling energy flows with high efficiency and low resource consumption. The aim of the project is to research new power electronic converters that enable a single-stage connection to the AC power supply grid for the first time through the use of gallium nitride (GaN) semiconductor components. The bidirectional blocking capability of these new semiconductor components is exploited here. To prove the functionality, a corresponding demonstrator is being realized and characterized with the industrial partners. (Source: https://elektronikforschung.de/projekte/enerconnect)

Based on the circuit topologies developed by the TU Berlin, the Fraunhofer IZM contributes the aspects relevant for industrial implementation.

These include the diverse requirements for practical application and the know-how regarding manufacturing methods. In addition, the Fraunhofer IZM also carries out the implementation in prototypes and enables test operation.
