Overview Timeline Barriers • Project start: October 2009 • Barriers • Project end: September 2012 – Capacitor Cost (up to 23% of inverter) • Percent complete (100%) – Thermal control – Volume (up to 23% of inverter) Budget • Total project funding Partners – DOE: $2800k • Electronic Concepts, Inc. • Funding received in FY09- • Sandia National Laboratories FY12 include: • FY09 - $350k • Penn State • FY10 - $750k • Argonne National Laboratories • FY11 - $850k • FY12 - $850k 2 Project Relevance • The Problem DC bus capacitors are currently the largest and the least reliable component of fuel cell and electric hybrid vehicle inverters. Capacitors represent up to 23% of both inverter weight and inverter cost and up to 35-40% of the inverter volume. In addition current thin
