WInSiC4AP contributes in developing reliable technology bricks for efficient and cost-effective applications addressing social challenges and market segments where Europe is a recognized global leader as well as automotive, avionics, railway and defence. Demonstrators: -On Board battery Charger for PHEV or BEV -Isolated DC-DC Converter for HEV, BEV and FC -Intelligent Power Switch (IPS-RA): High Voltage PowerConverters (<10 kV) for embedded railway equipment’s -Intelligent Power Switch (IPS-AA): AC & DC Intelligent Power Switch (IPS) for power distribution in avionics at module and component levels -High efficiency Bidirectional SiC-based Power Converter for V2G/V2H applications in a nano/microgrid scenario Inverter for Avionics Applications -LiPo Interface for Aerospace -Engine Controller-Inverter for Aerospace Reliability, efficiency improvements, cost and size reductions, designed-and manufactured-in-EU are the most relevant challenges addressed to lead to a strong European supply chain for SiC converters. The project will be supported with synergy by ECSEL JU and ESI funding, with relevant economic and social impact envisage in a less development region of Union. The ambition of WInSiC4AP is to play a primary role towards excellence in Europe: primary access to IPs for the relevant essential capabilities, competitiveness of manufacturing in Europe.
