Fully Integrated Autonomous Single-Tooth Module with Integrated SiC Power Electronics for Electric Drives


VERSE researches integrated drive systems based on silicon carbide (SiC) devices. The focus is on an autonomous single tooth (AEZ), a fully integrated single stator-tooth module with integrated SiC power electronics, sensors, logic and integrated communication. The AEZ is the answer to the conflicting challenges of specialization through system integration and a low-cost modular component system that is suitable for mass production. The research forms a milestone towards a further reduction of system costs.

The project addresses the following topics in detail:

  • Research on the AEZ as a fully integrated autonomous single-tooth module with robust and universal interfaces. Here, the challenges arising from the spatial proximity of the individual components and the universal applicability are particularly important.
  • Research on an autonomous, distributed control system. The aim is to enable a fault-tolerant operation and a high efficiency with the lowest possible communication requirements. The single-tooth structure without star point introduces particularly high demands on the control system.
  • Research on the winding insulation. The use of fast switching SiC semiconductors with high voltage gradients requires an investigation of the stress and the lifetime of the winding insulation systems.
