onsemi recently announced an expanded collaboration with motion technology leader Schaeffler through a new design win that utilizes onsemi’s next-generation EliteSiC silicon carbide (SiC) MOSFETs. The onsemi solution will power Schaeffler’s traction inverter for a global automaker’s advanced plug-in hybrid electric vehicle (PHEV) platform.
onsemi’s EliteSiC technology delivers significantly reduced conduction losses and enhanced short-circuit robustness, enabling a compact and thermally efficient inverter design. This translates into improved overall system performance. With the lowest on-state resistance in its class, the SiC-based solution ensures superior peak power output compared to other available options.
These advantages empower Schaeffler to develop an innovative traction inverter system that delivers measurable performance benefits to end users.
- Longer driving range, enabled by higher energy conversion efficiency
- Enhanced reliability, for consistent operation with lower maintenance
- Optimized form factor, allowing greater flexibility in vehicle design
“The traction inverter is at the heart of every electrified drivetrain, and onsemi’s EliteSiC solution plays a vital role in achieving the efficiency and performance targets that our customer demands,” said Christopher Breitsameter, Head of Business Division Controls at Schaeffler.
As automakers increasingly prioritize energy efficiency and performance, the industry is turning to more advanced hybrid architectures even in cost-sensitive EV platforms, a market traditionally dominated by insulated-gate bipolar transistors (IGBTs). onsemi’s role as an industry leader in silicon carbide positions it at the forefront of this transition, enabling Schaeffler to deliver an EV system that meets stringent performance and packaging requirements.
“As the exclusive silicon carbide supplier for this program, onsemi continues to strengthen its position as a trusted innovation partner for leading global automotive players,” said Simon Keeton, Group President, Power Solutions Group, onsemi. “Our industry-leading silicon carbide semiconductor technology delivers unmatched efficiency, thermal performance, and power density—key enablers for next-generation electric powertrain systems not only for battery electric vehicles, but also for plug-in hybrid platforms.”
This milestone builds upon the long-standing partnership between onsemi and Schaeffler (formerly Vitesco Technologies), further extending their multi-year collaboration. It reinforces both companies’ shared commitment to advancing high-efficiency electric mobility solutions.
