International Future Energy Challenge

The International Future Energy Challenge is an annual undergraduate student competition in the design of power electronic systems. The competition topic and location change every year. **Topic** Affordable Bidirectional Onboard Charger for Electric Vehicles **Specification** •Cost density: cost minimization (BOM to be presented) •Input voltage levels: dual 1?-AC input voltage @120Vac(60Hz) & 230Vac(50Hz) •Output voltage: 400 Vdc nominal (~150-450V) •Power: 1kW, bidirectional power capability, light load testing possible •Targeted efficiency: >92%@1kW ; >80% @100W •Targeted power density: 2 kW/l including cooling, EMI filters •Cooling: natural convection or self-supplied forced convection •Safety: galvanic isolation (Hipot test) •Testing: plug-and-play capability (without interface or interaction) •No real batteries will be used à bidirectional power supplies and resistive loads Full technical details will be announced soon. **Prizes:** There will be a Grand Prize of $10,000 and three additional awards granted at $5,000, $3,000 and $1,000 each. Competition metrics will include design considerations, measurement results, and innovation.
