- The latest agreement is a sign of their commitment to working together to develop innovative and sustainable mobility solutions.
- The Viper modules from BorgWarner will use Onsemi’s EliteSiC technology.
- This family of silicon and SiC power modules comprises 400V and 800V inverters.
- BorgWarner launched the Viper line in February and set the start of production for the new inverter program for 2025, with peak annual volume nearing 400,000.
- This is a significant development for the automotive industry and is a sign of the growing demand for SiC-based solutions.
- SiC is a more efficient material than silicon and can help to improve the performance and range of electric vehicles.
- The agreement will help to accelerate the adoption of SiC in the automotive industry and will help to make electric vehicles more efficient and sustainable.
Details
The partnership between BorgWarner and Onsemi is aimed at expanding the use of silicon carbide (SiC) technology in power modules for traction inverters, which are essential components in electric vehicles (EVs). By integrating Onsemi’s EliteSiC 1200 V and 750 V power devices into BorgWarner’s Viper modules, the companies expect to achieve several benefits:
- Increased Efficiency: SiC semiconductors in the inverters lead to higher efficiency, resulting in improved overall EV performance, faster charging speeds, and greater driving range.
- Smaller Inverters and Cooling Systems: The use of SiC technology allows for smaller inverters and corresponding cooling systems due to lower heat loss. This reduction in size helps to lower energy requirements in EVs.
- Enhanced Power Density: By using the new SiCs, BorgWarner can benefit from increased power density, allowing for more power to be handled within a smaller footprint.
- Strategic Investment in SiC Manufacturing: Onsemi’s continuous investment in ramping up SiC manufacturing capacity across its supply chain provides BorgWarner with confidence in meeting the increasing demand for their solutions in the present and future.
