onsemi has signed a multi-year deal with Volkswagen Group to be the primary supplier of a complete power box solution as part of its next-generation traction inverter for its Scalable Systems Platform (SSP).
The solution features silicon carbide-based technologies in an integrated module that can scale across all power levels – from high power to low power traction inverters to be compatible for all vehicle categories.
Based on the EliteSiC M3e MOSFETs, onsemi’s unique power box solution can handle more power in a smaller package which significantly reduces energy losses. The inclusion of three integrated half-bridge modules mounted on a cooling channel will further improve system efficiency by ensuring heat is effectively managed from the semiconductor to the coolant encasement. The company reports that this leads to better performance, improved heat control, and increased efficiency, allowing EVs to drive further on a single charge.
By using this integrated solution, Volkswagen Group will be able to easily transition to future EliteSiC-based platforms and remain at the forefront of EV innovation.
Volkswagen Group will also benefit from onsemi’s planned investment to expand its silicon carbide manufacturing in the Czech Republic. The investment would establish an end-to-end production facility in Europe for the traction inverter power system. The proximity of onsemi’s facility would fortify Volkswagen Group’s supply chain while improving logistics and allowing for faster integration into the manufacturing process.
