July 23, 2024 — On Semiconductor announced yesterday that it has been selected as a primary supplier for the main traction inverters of Volkswagen's Scalable Systems Platform (SSP). On Semiconductor will provide a comprehensive power module solution based on its advanced SiC (silicon carbide) technology for this platform.
The SSP, Volkswagen's unified electric vehicle platform designed for 80% of its next-generation vehicles, is slated for release in 2026.
On Semiconductor's power module solution will feature the newly launched EliteSiC M3e MOSFETs, introduced on July 18, 2024. These planar transistors significantly reduce energy consumption and handle higher power levels within a more compact package.
The company claims that the EliteSiC M3e MOSFETs offer a 30% reduction in conduction losses and up to a 50% decrease in switching losses compared to previous generations, with ultra-low on-resistance and enhanced short-circuit protection. The design of these components allows for a 20% reduction in material usage for the same output power.
In the complete power module solution, three integrated half-bridge modules are mounted on cooling channels, ensuring efficient heat transfer from the semiconductor devices to the coolant casing. This design improves system efficiency and extends the electric vehicle’s range.
Dirk Große-Loheide, Member of the Board of Management for Procurement at Volkswagen and a member of the Group Procurement Expansion Executive Committee, commented:
"We are thrilled to have On Semiconductor as a strategic supplier for the SSP platform’s main traction inverter power modules. Their vertically integrated supply chain, from raw material production to module assembly, reinforces our confidence in their capabilities."
Till von Bothmer, Senior Vice President of Powertrain Procurement at Volkswagen Group, added:
"Beyond vertical integration, On Semiconductor’s global network of SiC wafer facilities in Asia, Europe, and the US supports a flexible supply concept. Additionally, On Semiconductor’s commitment to providing the latest generation of silicon carbide technology ensures our competitive edge in the market."
