Periodic Reporting for period 1 - FastLane (Boosting the European Value Chain for Sustainable Power Electronics)
Reporting period: 2024-05-01 to 2025-04-30
The vision of FastLane is to build a comprehensive, highly competitive, sustainable and resilient all-European value chain for SiC-based power electronics, starting from powder and boules to engineered SiC substrates, enabling novel smart semiconductor devices, smart power modules and converters, that will address several EU key application domains. This will also ensure Europe’s sovereignty and reinforce the leading position of the EU power electronics industry.
The FastLane vision is addressed through five strategic and technical objectives:
1. Environmental footprint reduction: demonstrate an overall environmental footprint reduction all along the product life cycle
2. Sustainable European Sovereignty in Power Electronics: secure European sovereignty in SiC-based power electronics by establishing a strategic value chain, boosting the EU’s market position, aiming to increase production, reduce costs and improve processes.
3. Broaden SiC functionalities: enhance SiC devices functionalities by integrating on-die sensors to monitor the devices in situ, improving device, module and system protection with increased performance.
4. Overcome device-related limitations: overcome limitations thanks to advanced packaging, improved parasitics and fusion of in-die current measurement with integrated sensors.
5. Achieve cost benefits by reuse of automotive economy of scale: demonstrate how cost benefits can be achieved by reusing the economy of scale of automotive power electronics for other power conversion applications.
