Rohm provides SiC modules for Formula E team
Rohm is to supply full silicon carbide (SiC) power modules to the Venturi Formula E electric car racing team.

The inverter for season four features embedded full SiC Power Module, making it 43% smaller and 6 kg lighter than the inverter for season two. Rohm became Venturi’s technology partner last season and provides the SiC power devices used in the inverter, which is the core of the electric vehicle powertrain.

The key to victory in this racing series for the drivers is to use power as efficiently as possible by getting the maximum performance out of the stored energy. The advancement in Formula E technology is expected to filter through to developments in general-use electric vehicles. Although this motorsports event is still in its infancy, it already enjoys the participation of automotive manufacturers from around the world and major car makers including those from Japan have also declared their intention to take part in Formula E.

“The Formula E is the only motorsports event for testing the latest technology in next-generation electric vehicles,” said Franck Baldet, CTO of the Venturi Formula E Team. “By adopting a full SiC Power Module, we were able to bring to reality a lightweight inverter that requires only a minimum amount of space. By using the latest technology, I expect that we will be able to dramatically reduce our lap times.”
