Innovations in electronics will further increase the efficiency of electric vehicle propulsion systems and hence the range. Power electronics control the energy flows in the vehicle. The use of silicon carbide (SiC) semiconductors enables more efficient and thus more compact power electronics. Intelligent monitoring and control systems will ensure the reliability of future drives, even in the event of a fault.

The increasing share of photovoltaics and wind power in energy generation poses new challenges for energy grids. The converters that connect these sources to the grid lack intrinsic inertia, meaning that grid stability at times of high wind and photovoltaic generation is held up by an ever smaller number of synchronous generators. In order to guarantee the stability of networks with a high proportion of converters in the future, converters must provide an inertia similar to synchronous generators. A synchronous converter replicates the behaviour of a synchronous generator in order to provide a drop-in replacement for synchronous generation in power grids.
