onsemi to provide SiC power box solution for Volkswagen Group’s next-gen EVs – Charged EVs

Power and sensing technology specialist onsemi has signed a multi-year deal with the Volkswagen Group to be the primary supplier of a complete power box solution as part of a next-generation traction inverter for the automaker’s 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, in order to be compatible with all vehicle categories.

onsemi’s power box solution is based on the EliteSiC M3e MOSFETs. The inclusion of three integrated half-bridge modules mounted on a cooling channel is designed to improve system efficiency by ensuring that heat is effectively managed from the semiconductor to the coolant encasement.

“By offering a complete power system solution that encompasses the entire power sub-assembly, we provide Volkswagen Group with a single, simplified modular and scalable platform that maximizes efficiency and performance for their vehicle lineup,” said Hassane El-Khoury, President and CEO of onsemi. “This new approach allows for the customization of power needs and the addition of features for different vehicles without compromising on performance, all while reducing cost.”

“We are pleased to have onsemi as a strategic supplier for the power box of the traction inverter for our first tranche in the SSP platform. onsemi has convinced us with a deeply verticalized supply chain from the growth of the raw material up to the assembly of the power box,” said Volkswagen Board Member Dirk Große-Loheide.
